Kim Hye Joon Faces Fan Dreams And Office Romance In My Bias, My Boss Trailer

tvN has released a fuller look at My Bias, My Boss, setting up a workplace romance built around idol fandom, second chances, and an awkward first impression that refuses to stay in the past.

The upcoming series stars Kim Hye Joon as Nam Da Reum, an office worker whose career move is driven by a deeply personal goal: getting closer to Lee Chan, the idol she has admired since her teenage years. Cha Woo Min plays Lee Chan, a member of the fictional group D.N.X, while Kang Hoon plays Kang Ha Gi, the company executive who becomes an unexpected obstacle and possible romantic rival.

A Fan Dream Becomes A Career Gamble

The highlight trailer introduces Da Reum as more than a casual fan. Her connection to Lee Chan goes back to age 17, when his songs helped her through loneliness. That history turns her admiration into something formative, making her decision to leave a coveted major-company job for a fashion startup feel both risky and emotionally understandable.

Da Reum joins Apello believing the move will put her in the same orbit as Lee Chan. Instead, she quickly learns that the company is no longer organized the way she expected. Her search for the idol leads to a blunt answer from a coworker: the business has shifted to a one-CEO system, and the person at the top is not the star she came to find.

That twist puts Kang Ha Gi directly in her path. The problem is that Da Reum and Ha Gi have already met under disastrous circumstances outside the office, with her drunken behavior leaving a bad impression before either of them understood they would be working together. Their early workplace dynamic is tense, chilly, and uncomfortable, with Ha Gi keeping his distance as Da Reum tries to repair the damage.

From Idol Admiration To Office Conflict

The trailer also shows Da Reum finally achieving part of her original dream. She meets Lee Chan, shakes his hand, and begins moving from distant admirer to someone who can interact with him directly. Those moments frame her as a so-called successful fan, but the drama complicates that wish almost immediately by placing it inside a competitive workplace.

Da Reum’s new job does not stay lighthearted for long. The preview suggests she comes under suspicion of being a corporate spy, forcing her to prove herself through effort and persistence. That storyline gives the series a broader engine than simple celebrity wish fulfillment: Da Reum must show that her reasons for joining the company do not erase her ability to work seriously once she is there.

As she settles into Apello, Ha Gi begins to soften. The trailer hints that his guarded attitude gradually gives way to interest, creating a contrast with Lee Chan’s more direct and flirtatious approach. What begins as Da Reum chasing an idol-centered dream becomes a triangle shaped by two different kinds of attention: the familiar pull of a longtime bias and the unexpected closeness of a boss who has seen her at her worst.

A Rom-Com Built Around Modern Fandom

My Bias, My Boss is based on a webtoon of the same name, and the premise taps into a distinctly modern entertainment fantasy. It asks what happens when fan devotion crosses into professional life, but it also appears to treat Da Reum’s feelings as part of her personal history rather than a simple punchline. Her fandom is the reason she takes the leap, yet the trailer suggests the story will test whether that leap can become something more mature.

The setup also gives Kim Hye Joon a character who can move between comedy, embarrassment, determination, and romantic confusion. Da Reum is not presented as passive; she makes a bold choice, absorbs the consequences, and keeps moving even when the reality of her new job does not match the fantasy that brought her there.

For Kang Hoon and Cha Woo Min, the trailer positions their characters as opposing romantic energies. Ha Gi represents the difficult present of office life, authority, and slowly earned trust. Lee Chan represents the emotional past that gave Da Reum comfort and the glamour that first drew her to Apello. The drama’s central question is not only which man she will choose, but what version of herself she wants to become.

My Bias, My Boss is scheduled to premiere on August 3 at 8:50 p.m. KST and will be available on Viki. With its blend of fandom culture, startup pressure, and romantic misdirection, the series is positioning itself as a late-summer office rom-com with a K-pop-adjacent hook.
