Kim Hye Joon Faces Fangirl Dilemma in New My Bias, My Boss Teaser

tvN is sharpening the romantic conflict at the center of My Bias, My Boss, releasing a new teaser that places Kim Hye Joon’s character between the fantasy of idol fandom and the reality of a fast-moving workplace.

The upcoming drama, adapted from the webtoon of the same name, follows Nam Da Reum, a passionate fan who takes a job at the fashion startup Apello because it brings her closer to Lee Chan, the idol she has long admired. Kim Hye Joon plays Da Reum, while Cha Woo Min appears as Lee Chan and Kang Hoon plays Kang Ha Gi, the company’s CEO.

The new teaser leans into the series’ central hook: Da Reum starts out with a clear goal, but the office she enters is not just a shortcut to her favorite star. It becomes the place where her professional ambition, fan identity, and unexpected feelings begin to overlap.

In the footage described by Soompi, Da Reum is shown working hard at Apello, where a large banner of Lee Chan dominates the company building. Even while exhausted, she pushes herself to become the kind of employee who stands out, declaring that she wants to become the favorite employee no matter what.

A Workplace Built Around a Fangirl Premise

That setup gives My Bias, My Boss a familiar but commercially strong K-drama engine. The story is not only about whether a fan can meet her idol. It is also about what happens when admiration becomes part of a workplace, and when the person who seems like the dream choice is no longer the only person who matters.

The teaser’s most revealing moment comes when Da Reum trips and the contents of her bag spill out. Her belongings, including idol merchandise and an official light stick, expose how deeply her daily life is tied to D.N.X, the fictional group connected to Lee Chan. Even her phone lock screen and music make her loyalty impossible to hide.

The scene then turns into a romantic crossroads. Two men help her at the same time and ask if she is all right: Lee Chan, the idol she came to the company hoping to see, and Kang Ha Gi, the CEO who begins to complicate her feelings. Da Reum’s narration frames the moment as the arrival of a new bias in her life as a fangirl.

Kim Hye Joon Leads a Webtoon Romance With Idol-Culture Appeal

For Kim Hye Joon, the role offers a bright romantic-comedy contrast to the darker and more intense projects many viewers associate with her. Da Reum’s character depends on a balance of sincerity and embarrassment: she has to be funny because her fandom is so visible, but believable because her emotions are treated as more than a joke.

Kang Hoon’s Kang Ha Gi appears positioned as the unexpected challenger to Da Reum’s long-established idol crush. Rather than simply playing the polished executive, the character’s function in the teaser is to create a different kind of attraction: close, immediate, and tied to Da Reum’s actual working life.

Cha Woo Min’s Lee Chan, meanwhile, remains essential to the premise because he represents the idealized pull that brings Da Reum into Apello in the first place. The drama’s tension will likely depend on whether Lee Chan stays a distant dream, becomes a genuine romantic possibility, or forces Da Reum to rethink what being a fan means once real people are involved.

The timing also gives tvN a clear promotional lane. K-dramas built around webtoon IP and fandom language have become increasingly accessible to international viewers, especially when the story uses idol culture as a doorway into broader themes of work, identity, and first love. My Bias, My Boss appears designed to speak directly to viewers who understand how a celebrity favorite can become part of everyday motivation.

Premiere Plans

My Bias, My Boss is scheduled to premiere on August 3 at 8:50 p.m. KST. The drama will also be available on Viki, giving the series a path to reach global viewers soon after its Korean broadcast.

The teaser ends by withholding Da Reum’s final choice after she announces, “My bias is…” It is a simple cliffhanger, but it neatly sells the drama’s main question: whether the person who inspired her dream will remain her heart’s answer once her real life starts changing.
