ITZY’s Yuna Steps Into Rising Actress Role for tvN’s My Bias, My Boss

tvN’s upcoming romance drama My Bias, My Boss is adding another familiar K-pop face to its growing character lineup. ITZY’s Yuna has been introduced in the role of Yoon Choi, a rising actress whose professional life and private feelings are set to complicate the story’s idol-centered romance.

The drama is based on the webtoon of the same name and follows Nam Da Reum, a devoted fan who joins a company with the hope of getting closer to her longtime idol bias. Instead of finding a simple route toward her celebrity crush, she becomes entangled with Kang Ha Gi, the CEO of the fashion startup Apello. That workplace setup gives the series a mix of fan culture, office romance, and celebrity drama, placing private emotions inside a very public industry.

Kim Hye Joon stars as Nam Da Reum, the fan whose decision to enter Apello drives the central premise. Kang Hoon plays Kang Ha Gi, the CEO who becomes unexpectedly close to her after she joins the company. Cha Woo Min appears as Lee Chan, the idol at the center of Da Reum’s fandom and the character whose relationships appear likely to pull several storylines together.

Yuna’s Character Adds Celebrity Tension

Yuna’s character, Yoon Choi, is described as a newly prominent actress with both star quality and striking public appeal. In the drama’s setup, Yoon Choi gains major attention soon after her debut and quickly becomes a figure audiences recognize. Her popularity is not only built around image; she also earns a warm response for her screen chemistry with Lee Chan in a romance project.

That professional chemistry becomes personal during filming. As Lee Chan helps Yoon Choi rehearse lines between takes, she begins to develop feelings for him. The drama positions her emotional turn as something shaped by both the intimacy of acting and the confusion that can come when fictional romance starts to feel real. After becoming deeply immersed in her role, Yoon Choi decides she wants to move beyond being co-stars and pursue Lee Chan outside the scripted relationship.

This development gives My Bias, My Boss another angle beyond its headline fan-meets-idol premise. Instead of focusing only on Nam Da Reum’s admiration for Lee Chan, the series appears to build a wider romantic field around him. Yoon Choi’s bold pursuit introduces rivalry, uncertainty, and questions about how public personas affect private decisions.

A Webtoon Romance Built Around Fandom

The core appeal of My Bias, My Boss is its use of modern fandom as a starting point for romance. Nam Da Reum’s choice to work at Apello is not a neutral career move; it is tied to her desire to be near Lee Chan. That premise gives the drama room to explore how admiration, ambition, and workplace reality collide once a fan steps into the professional orbit surrounding a star.

At the same time, the addition of Yoon Choi suggests the series is not treating celebrity as a distant fantasy. Her character is already inside the entertainment world, dealing with scripts, public appearances, and the blurred emotional lines that can emerge on set. Newly released stills show Yoon Choi in contrasting spaces: one at a red-carpet event and another focused on a script, underlining the difference between polished public image and the work behind it.

For Yuna, the role also keeps attention on the growing overlap between idol careers and acting projects. K-pop performers frequently move between music, variety, fashion, and drama, but each role still carries its own test. Playing Yoon Choi gives Yuna a character whose celebrity status is part of the plot rather than just background detail, which may make the role especially visible to both ITZY fans and drama viewers.

Premiere Date and Viewing Details

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 international viewers a route to follow the story as it airs. With its webtoon origins, office setting, idol-fan premise, and cast of characters moving between private feelings and public roles, the series is positioned as a light but emotionally tangled romance.

The latest character preview does not reveal how far Yoon Choi’s pursuit of Lee Chan will go, or how it will affect Nam Da Reum’s own journey inside Apello. What it does make clear is that the drama is building more than a simple fantasy about meeting a favorite star. By placing an actress, an idol, a fan-turned-employee, and a CEO into the same romantic space, My Bias, My Boss is setting up a story where admiration and real connection may not point in the same direction.
