Bona spent years preparing for an idol debut, entered acting without formal acting classes, trained for months to look convincing as an elite fencer, and later studied real shamanic rituals for a fantasy historical role.
That progression makes Kim Ji Yeon more interesting than a simple singer-turned-actress story: each stage of her career has required her to learn a different performance language.
Who Is Bona?
Bona, whose real name is Kim Ji Yeon, is a South Korean singer, dancer, and actress under Starship Entertainment.
She debuted with WJSN in 2016 before entering television through Hit the Top in 2017, then developed a separate acting identity through Girls’ Generation 1979, Your House Helper, Homemade Love Story, Twenty Five Twenty One, Joseon Attorney: A Morality, Pyramid Game, and The Haunted Palace.
Her ability to move between idol performances, sports drama, school thriller, historical storytelling, and fantasy has made the Daegu-born performer increasingly difficult to define by only one side of her career.

How Old Is Bona?
Bona is 32 years old in 2027. Born on August 19, 1995, the Korean actress is a Leo, a zodiac sign traditionally associated with confidence, creativity, loyalty, expressive energy, and a natural comfort with performance.
Those characteristics make an interesting match with someone whose professional life developed on both music stages and drama sets.
Ji Yeon spent years preparing within the competitive idol system before taking on acting, where the rewards come from a very different kind of emotional expression.
Her own comments reveal an increasingly relaxed attitude toward ambition. After years of focusing on reaching goals as quickly as possible, the WJSN member explained that she became more interested in finding a way to enjoy the process, a shift that fits the more exploratory direction of her acting career.
Where Is Bona From?
Bona is from Daegu, South Korea, and that hometown connection became unexpectedly useful when acting entered her career.
Her natural familiarity with the Daegu dialect helped her portray Lee Jung-hee in Girls’ Generation 1979, a drama set in the city during the late 1970s.
The Daegu-born entertainer spent her school years there before the demands of trainee life pulled her more deeply into Seoul’s entertainment industry.
Music training occupied a major part of the years leading to her WJSN debut, giving Ji Yeon an unusually disciplined professional routine before she ever stepped into a substantial acting role.
That background also created a personal connection with Twenty Five Twenty One. Bona has explained that trainee life left her with fewer conventional school memories, so portraying elite fencer Go Yu-rim allowed her to experience emotions and friendships that felt almost like creating another set of memories for herself.

How Tall Is Bona and What Are Her Physical Features?
Bona stands approximately 163 cm, or about 5 feet 4 inches tall. Her proportions translate comfortably across stage costumes, school uniforms, traditional hanbok, tailored suits, feminine dresses, denim, and relaxed streetwear, giving stylists considerable freedom to change her visual identity between music and acting.
Dark eyes, balanced facial features, and a softly defined face allow the Korean screen performer to move between delicate and sharper styling without needing excessive makeup.
Long waves can emphasize a romantic mood, while straighter hair, restrained makeup, or cleaner tailoring creates a more controlled impression.
Her actress profile photographs demonstrate that contrast particularly well. Light makeup and simple hair highlighted a fresh, understated side, while a sleek white suit and more structured posing produced a noticeably stronger and more sophisticated image.
We think her most useful visual quality is adaptability rather than one fixed feature. The same face that works with elaborate idol styling can appear remarkably different under the stripped-back makeup of a thriller, the athletic styling of a fencing drama, or the formal hair and costume of a historical production.
That ability has even become something Bona herself recognizes as an acting advantage.
Viewers sometimes failed to immediately connect her drama appearance with her idol image, and she came to appreciate that separation because it allowed audiences to see the character before seeing the performer.
What Is Known About Bona’s Personal Life and Relationship Status?
Bona keeps romance outside the center of her public persona and has not announced a marriage or a publicly confirmed partner.
Interviews tend to reveal much more about her work ethic, friendships, group relationships, and changing outlook on life than about private dating.
WJSN occupies an especially meaningful place in that personal story. Ji Yeon spent years training before debut, lived through the adjustment of working inside a large group, and has spoken about how the members learned to understand different personalities while supporting one another through difficult periods.
Financial independence became another memorable milestone. During an appearance on Ask Us Anything, the singer-actress explained that earning and spending her own money had been on her bucket list, making the move from relying on her mother’s credit card to having one under her own name personally meaningful.
Her friendships also cross different corners of Korean entertainment, but the strongest public bond remains the one built through WJSN.
Years of rehearsals, recordings, performances, competitions, and individual schedules created a shared history that Bona has described as a major part of her personal growth.
Bona’s Career Journey in the Creative Industry
Bona’s professional career began long before her television debut. She spent several years as an idol trainee, describing a period where competition was intense and progress could feel uncertain, yet her response was generally practical: concentrate on the things she could control and continue working.
That preparation led to WJSN. Starship Entertainment debuted the group in February 2016, placing Bona within a lineup built around vocals, choreography, elaborate visual concepts, and the group’s cosmic identity. She also became part of WJSN THE BLACK, a sub-unit that explored a sleeker and more mature performance concept.
Music gave the idol performer more than stage experience. Rehearsing choreography, learning camera positions, maintaining consistency across repeated performances, and understanding how expression reads from a distance all became skills that could later support screen work.
Acting entered the picture with Hit the Top in 2017. A larger opportunity followed almost immediately through Girls’ Generation 1979, where Bona played energetic high school student Lee Jung-hee in a story set in her hometown of Daegu.
The route into that role was wonderfully unconventional. Ji Yeon has explained that she had never taken acting classes, and when auditioning for a teenage character she arrived wearing a school uniform because her agency had suggested it. Her natural Daegu dialect then became another practical advantage for the part.
Your House Helper gave her a contemporary workplace character through advertising-company intern Im Da-young.
Costume styling leaned into colorful blouses, office-ready blazers, and neat professional separates, allowing the idol-actress to embody both the frustration and optimism of someone trying to establish herself at work.
Family drama expanded that experience through Homemade Love Story. As Lee Hae-deun, Bona joined a long-form weekend production and earned Best New Actress recognition at the 2020 KBS Drama Awards, an important acknowledgment of the acting career she had been building alongside music.
An earlier industry honor had already reflected that dual identity. The 2019 Korea First Brand Awards named WJSN’s Bona the Female Idol-Actor winner, recognizing a performer whose music and screen careers were beginning to develop side by side.
Then came Twenty Five Twenty One. As Go Yu-rim, Bona played a national fencing champion whose competitive exterior hides family pressure, vulnerability, and a complicated relationship with Kim Tae-ri’s Na Hee-do.
Preparation went much further than learning a few convincing poses. Ji Yeon trained in fencing for about three months before filming, giving her enough familiarity with footwork, posture, equipment, and repetition to make Yu-rim’s identity as an elite athlete feel embedded in the performance.
The role also changed how some viewers perceived her. Bona said she was grateful when people were surprised to learn that she came from an idol background, particularly because she wanted audiences to concentrate on Yu-rim rather than on assumptions about singer-actors.
Her chemistry with Kim Tae-ri became another defining element. The two actresses spent considerable time learning fencing together before shooting, giving the rivalry and eventual friendship between their characters a physical familiarity that had been built outside the scripted scenes.
WJSN activities continued alongside that acting growth. The group competed on Mnet’s Queendom 2 and ultimately won the competition, adding another high-profile performance achievement to Bona’s music résumé.
Historical drama offered the next major transformation. Joseon Attorney: A Morality cast Ji Yeon as Princess Lee Yeon-joo, a royal figure who hides her identity while pursuing justice and revenge after her father’s death.
It was her first historical drama, meaning costume, speech, movement, and emotional rhythm required adjustment from contemporary productions.
The character also gave Bona opportunities to appear in several disguises, including male clothing, further expanding the visual and dramatic range attached to her filmography.
Pyramid Game moved almost completely away from palace romance. As transfer student Sung Su-ji, the WJSN actress led a school thriller built around a cruel popularity-ranking system that designates one student as a target for violence.
Su-ji is strategic rather than conventionally heroic. She studies the social structure around her, refuses to accept the rules passively, and looks for ways to dismantle the system through intelligence and psychological maneuvering rather than relying solely on physical retaliation. Bona described “mind game” as an essential keyword for understanding the drama.
Action training became part of the preparation as well. Ji Yeon attended an action school so that physical scenes could be performed safely, and the experience left her interested in challenging herself with more action-oriented work.
Fantasy historical drama opened another door through The Haunted Palace. As Yeo-ri, Bona plays a woman born into a powerful shamanic family who rejects that destiny and instead wants to live as an artisan before supernatural events pull her back toward the spiritual world.
The preparation was unusually specific. The Daegu-born actress consulted real shamans, observed rituals, studied chants, and practiced ritual movement so the supernatural setting could still contain believable physical details. Korean dance elements also became part of the exorcism sequences.
That work brought one of her strongest acting honors. Ji Yeon received the Top Excellence Award in the Human/Fantasy Miniseries category at the 2025 SBS Drama Awards for The Haunted Palace, sharing the category’s top recognition with Yook Sung-jae.
Her drama range continues through Disney+’s Dive Into You, where Bona is cast as Yoon Ha-na, a famous actress who exchanges bodies with her twin brother and travels into the past while trying to prevent the death of her first love.
The premise combines fantasy romance, body-swapping, emotional disconnection, and time travel, offering another character unlike the athlete, princess, student strategist, and shaman already in her résumé.
Commercial work has developed alongside both music and acting. Seoul Milk selected Bona for its Viyott yogurt advertising, while British-inspired footwear and outerwear label Rockfish Weatherwear worked with her on a summer collection that mixed dresses, rain boots, shorts, shirts, and more androgynous styling.
What Is Bona’s Signature Fashion Style?
Bona’s wardrobe has a feminine base, but denim and relaxed streetwear keep it from becoming overly delicate.
Her off-duty looks move comfortably between jeans, cropped jackets, simple tops, leather outerwear, cargo trousers, dresses, sneakers, caps, and compact shoulder bags.
Denim is one of the clearest recurring elements. Ji Yeon has worn ripped jeans with simple white tops, layered denim jackets over dresses, cropped denim with cargo pants, and looser blue washes that give more polished pieces an everyday edge.
Black adds the sharper side of the palette. Leather jackets, black dresses, dark accessories, and fitted tops introduce contrast, particularly when paired with denim or lighter fabrics rather than styled as a completely severe monochrome look.
Soft neutrals occupy the opposite end. White, ivory, beige, cream, pale blue, and muted gray complement her naturally clean image, while pink, red, floral prints, and brighter accents preserve the playful femininity associated with her idol styling.
The Rockfish Weatherwear campaign captured that versatility particularly well. Bona appeared in romantic dresses with boots but also shifted into shirts and shorts with a more androgynous city-inspired mood, showing how easily her image can move between sweet and understated cool.
Her actress profile photography takes minimalism further. A sleek white suit, restrained jewelry, clean hair, and natural makeup allowed silhouette and expression to do most of the work, creating a mature contrast with the more decorative styling often used for K-pop performances.
We especially like that she does not need one fixed fashion character to remain recognizable.
A floral mini dress, worn denim, structured suit, rain boot, or black leather jacket can all work because the overall styling usually keeps one idea in focus instead of stacking too many statements together.
Editorial fashion has also benefited from her ability to control expression. An ELLE shoot inspired by Go Yu-rim placed elegant clothing beside fencing equipment, turning a sports prop into part of a chic visual story rather than treating athletics and fashion as separate concepts.
Hair and makeup provide another layer of contrast. Idol styling can use stronger eye definition, glossy lips, elaborate hair, and more visible color, while her acting portraits often favor soft complexion work, natural brows, simple hair, and restrained lips.
That difference has become part of her professional advantage. Instead of forcing the same beauty identity across every platform, the singer-actress lets makeup support the role, campaign, or stage concept, giving her visual portfolio far more range.

What Is Bona’s Estimated Net Worth?
Bona’s financial footprint reflects two careers that developed in parallel rather than one isolated source of work. WJSN albums, performances, concerts, sub-unit activities, television dramas, leading acting roles, advertising, magazine shoots, and branded fashion projects all sit within the same professional history.
Her personal net worth is undisclosed, while her career has included several milestones tied directly to financial independence.
Ji Yeon has spoken about reaching the point where she could manage her own spending after years of trainee life, describing that independence as something she had wanted to achieve for herself.
Acting has steadily increased its weight within that picture. Long-form family drama gave way to prominent roles in Twenty Five Twenty One, Joseon Attorney: A Morality, Pyramid Game, The Haunted Palace, and Dive Into You, allowing her name to move from ensemble billing toward projects where she carries a major portion of the story.
Commercial campaigns add another stream through brands such as Seoul Milk’s Viyott and Rockfish Weatherwear.
The latter also connects her acting and idol visibility with fashion, footwear, and lifestyle advertising rather than limiting her brand appeal to one consumer category.
WJSN provides another long-running professional foundation. Group albums, stage performances, WJSN THE BLACK, and the group’s Queendom 2 victory form part of a music career that continues to sit alongside Ji Yeon’s increasingly substantial acting résumé.
Inside Bona’s Lifestyle, Beauty, and Daily Routines
Bona’s approach to work seems shaped by years of learning how to prepare intensely without treating every result as something she can control.
She has spoken about focusing on what she can actually change rather than spending too much energy on circumstances outside her influence, a practical outlook formed through trainee life and entertainment work.
Physical preparation changes with each acting project. Fencing became part of everyday training for Twenty Five Twenty One, action classes supported Pyramid Game, and ritual movement, chanting, and elements of Korean dance entered her preparation for The Haunted Palace.
That pattern suggests a lifestyle where fitness is often connected with craft rather than one permanent celebrity workout formula.
The idol background already demands dance stamina and body awareness, while acting adds specialized movement whenever a character requires another physical vocabulary.
Travel gives her digital image a much softer side. Photographs from a Bali trip showed Ji Yeon swimming, spending time by the sea, and favoring casual resort clothing, offering a relaxed contrast with the disciplined environments of rehearsals and drama sets.
Beauty styling tends to shift depending on whether she is working as Bona the idol or Kim Ji Yeon the actress.
The performer herself has noted how dramatically different she can appear with actor-oriented styling, eventually viewing that separation as useful because it helps individual characters establish their own identity.
Her King Kong by Starship profile photographs provide a strong example of the actress side. Light makeup, clean skin, softly styled hair, and minimal detailing created a fresh appearance, while a white suit and controlled pose moved the same beauty look toward quiet sophistication.

What Can We Learn from Bona’s Success Story?
Bona’s career shows why training in one discipline can become useful even when another profession starts demanding more attention.
Years of choreography taught consistency, stamina, camera awareness, and teamwork before acting required her to translate those instincts into subtler emotional choices.
Her entry into acting is particularly instructive because she did not begin with a perfect technical foundation.
Ji Yeon openly acknowledged that she had not taken acting classes, yet each production became another place to learn rather than proof that she needed to stay only within music.
The fencing preparation for Twenty Five Twenty One illustrates that mentality clearly. Instead of depending on editing to create the illusion of an athlete, the idol-actress spent months practicing enough of the sport to understand the physical habits behind Go Yu-rim.
She approached The Haunted Palace in much the same spirit, only the subject changed completely. Rituals, chants, Korean dance, and conversations with shamans became the research tools for Yeo-ri, showing that serious preparation can take a different shape for every character.
We think the strongest lesson comes from the way she responds to labels. Instead of distancing herself from being an idol when people questioned singer-actors, Bona embraced that part of her identity while continuing to improve enough that some viewers eventually saw only the character.
That makes her progression feel more substantial than simply replacing one career with another. WJSN, acting, fashion, dance, and commercial work remain connected, while the skills required for each field continue feeding into the others.
