Kim Hye-jun Turns Ultimate Fangirl in Favorite Employee

Kim Hye-jun is stepping into the kind of fan fantasy that many K-drama viewers will understand immediately: what if the office badge replaced the concert lightstick? tvN's upcoming Monday-Tuesday drama Favorite Employee has released a new teaser that positions Kim's character, Nam Da-reum, as an idol fan whose devotion leads her all the way into her favorite star's workplace.

The series is scheduled to premiere on August 3 at 8:50 p.m. KST, and its setup blends office romance, coming-of-age comedy, and the language of modern fandom. Rather than treating fan culture as a side joke, the drama builds its entire premise around the emotional logic of "successful fan" culture, where admiration, ambition, and proximity all collide inside a professional setting.

For international viewers, that premise lands in a familiar but distinctly Korean space. K-pop fandom has its own vocabulary, rituals, and social codes, and Favorite Employee appears ready to turn those details into the engine of a workplace story. The teaser's central gag is simple: Da-reum does not merely go to concerts to see her favorite idol. She goes to work.

A Fangirl Premise With Office-Romance Stakes

In the drama, Kim Hye-jun plays Nam Da-reum, a devoted fan of the fictional idol group D.N.X. Her favorite member is Lee Chan, played by Cha Woo-min, and Da-reum's desire to get closer to him pushes her toward a drastic life choice: she joins Apello, the fashion platform connected to Chan's professional world.

The new "successful fan" teaser frames that choice with a playful sense of escalation. Da-reum begins in the crowd at a concert, where the emotional temperature is high and her fandom is public, loud, and uncomplicated. The scene then shifts to the office, where the same fan energy has to survive under fluorescent lights, employee IDs, meetings, and the pressure to act like a functioning adult.

That contrast gives the series its clearest hook. Da-reum is not just chasing a celebrity from a distance; she is trying to turn a fan's dream into an everyday routine. The office becomes a new kind of stage, filled with posters, music, and reminders of the idol world she has followed for years, but it is also a place where mistakes have consequences and fantasies can run into real hierarchy.

The teaser's joke is that Da-reum treats employment itself like the ultimate fan event: not a ticketed night out, but a daily pass into the same orbit as her favorite star.

That angle could give Favorite Employee a broader appeal than a standard workplace rom-com. Viewers who know fandom culture may recognize the exaggerated sincerity of Da-reum's mission, while viewers who are less familiar with K-pop can still follow the universal story of someone trying to belong in a world that both excites and intimidates her.

Why Kim Hye-jun's Casting Matters

Kim Hye-jun's move into this role is notable because the actress has built much of her reputation through sharp genre turns rather than light romantic comedy. Korean reports highlight her past work across films such as Another Child, Metamorphosis, and Sinkhole, as well as dramas including Inspector Koo, Connect, and A Shop for Killers.

Her recent Netflix role in Cashero also reinforced her image as an actor comfortable with capable, alert characters who carry practical intelligence. That history makes Nam Da-reum interesting on paper. The character is comic and openly emotional, but she also has to be active enough to make an extreme decision feel like more than a sketch-comedy premise.

The drama's early character description suggests that Da-reum is not simply a passive fan waiting to be noticed. She is an 11-year devotee of D.N.X who is willing to give up a more conventional path and enter a startup environment because of her feelings for Lee Chan. That detail gives the role an edge of stubbornness, and it gives Kim room to play both earnestness and professional awkwardness.

The setup also creates an obvious tension around identity. At work, Da-reum must become a new employee who can contribute to Apello. In her private emotional life, she remains a fan whose heart still reacts to every sign of Lee Chan's presence. The drama's challenge will be to make those two versions of Da-reum clash in funny ways without reducing her to a one-note fangirl.

A Webtoon Story Rebuilt for tvN

Favorite Employee is based on the popular Naver webtoon Our Oppa Is an Idol. That source material matters because webtoon adaptations have become one of Korean television's most reliable pipelines, especially for stories with a clear visual concept and a built-in younger audience.

The production team includes writers Lee Young and Kim Ji-an, with Park Ji-hyun and Jung Da-hyung directing. Reports also identify Studio Dragon, Studio N, and NPIO among the companies behind the drama, placing the project inside a familiar network of Korean drama production and webtoon adaptation expertise.

The cast expands the story beyond Da-reum and Lee Chan. Kang Hoon appears as Kang Ha-gi, the representative of the fashion startup Apello, while ITZY's Shin Yuna is also part of the lineup. That combination points toward a drama that may split its energy between office politics, idol-world proximity, and romantic complication.

For global K-drama fans, the fictional group D.N.X is an especially useful device. By inventing its own idol group, the drama can borrow the emotional structure of real K-pop fandom without tying itself too tightly to a real act's history. It can exaggerate fan rituals, workplace coincidences, and backstage-style longing while keeping the story flexible.

Fan Culture as the Main Story, Not Decoration

What makes the teaser stand out is the way it treats fan culture as a serious comic premise. The Korean word "seongdeok," often used for a fan who achieves a dream-like encounter or opportunity involving their favorite star, sits at the center of the promotional framing. Da-reum is not just lucky; she is trying to engineer her own version of that dream.

The fantasy is easy to understand. Many fans have imagined being noticed by an artist, working near the industry, or turning years of passion into something more tangible. Favorite Employee pushes that wish to its most literal point by asking what happens when the fan actually clocks in at the same company connected to the idol she admires.

At the same time, the premise contains built-in discomfort. A workplace is not a fan meeting. Da-reum's enthusiasm may help her survive the emotional shock of being near Lee Chan, but it cannot replace competence, boundaries, or the ability to navigate relationships with colleagues who do not share her private motivation. That is where the drama's growth element can emerge.

The teaser's use of office imagery also suggests that the series will have fun with the contrast between fandom objects and corporate objects. A lightstick becomes an employee badge in spirit; the concert crowd gives way to coworkers; the idol poster becomes part of the workday environment. Those swaps are funny because they translate fan emotion into adult routine.

If handled well, the show could speak to viewers who have had to negotiate the same divide in real life. Fandom often begins as escape, but adult life asks people to fold their passions into schedules, careers, and social expectations. Da-reum's story turns that negotiation into a rom-com engine.

What to Watch Before the Premiere

With the August 3 premiere date now attached to the latest teaser cycle, the key question is how much of Favorite Employee will lean into comedy and how much will develop Da-reum's professional growth. The strongest version of the premise would allow her to be both ridiculous and capable: a fan whose feelings are huge, but whose ambitions are not limited to being near Lee Chan.

Cha Woo-min's Lee Chan also has to carry more than the aura of an idol crush. Because Da-reum's entire decision is built around him, the character will need enough texture to justify both her fascination and the complications that follow. If he remains only a fantasy object, the story risks becoming thin; if he has his own career pressures and emotional blind spots, the office romance could gain real shape.

Kang Hoon's role as Kang Ha-gi may be equally important. As the figure tied to Apello's leadership, he can represent the reality principle inside Da-reum's dream job. His presence also opens the door for a triangle or at least a competing emotional rhythm between fantasy, work, and genuine human connection.

For now, Favorite Employee has a clean pitch: a longtime idol fan enters the workplace of her favorite star and discovers that becoming a "successful fan" may be far more complicated than getting close to the person she admires. That is enough to make the drama one of tvN's more curiosity-friendly summer entries, especially for viewers drawn to stories where fandom is not background noise but the starting point of the whole plot.
