Seo In Guk and Park Ji Hyun will team up in the upcoming 2026 tvN drama “Let’s Go to Work Tomorrow!” (written by Kim Kyung-min, directed by Jo Eun-sol). The office romance follows Ji Yoon, a seventh-year employee stuck in a career slump, who chooses her prickly boss Si Woo as the “lesser evil” — only to find him becoming her irreplaceable “best choice”.
The drama is based on the hit McQueen Studio webtoon of the same name, which has amassed over 200 million views. Known for its realistic office setting and sweet romantic elements, the webtoon sparked fan casting since its release, and anticipation is high for the first on-screen pairing of the two stars.

Seo In Guk plays Kang Si Woo, Ji Yoon’s direct supervisor — a “face genius” with perfect looks, impressive stature and exemplary self-discipline, but also a cold and blunt personality that has earned him the title of “the company’s most irritable man”. His complicated connection with Ji Yoon slowly unfolds over time.

Dubbed the “King of Romance”, Seo has captivated viewers in Reply 1997, High School King of Savvy, Shopping King Louie, The Smile Has Left Your Eyes and Doom at Your Service, and recently earned praise for his acting in Death’s Game. Fans are eager to see him bring his proven romantic charisma to this new role.

Park Ji Hyun will portray Cha Ji Yoon, a capable and trusted K-office veteran with deft skills and sharp instincts who handles every task with ease. However, she finds herself in a slump in both work and love. Her ordinary routine takes a sharp turn when her irritable boss, Kang Si Woo, suddenly becomes a part of her personal life. Park has showcased her versatility across romance, action and thriller in Do You Like Brahms?, Yumi’s Cells, Reborn Rich, Flex X Cop and the film Hidden Face. Her ability to embody diverse characters raises anticipation for how she will portray Ji Yoon, as well as for her chemistry with Seo In Guk.
“Let’s Go to Work Tomorrow!”, starring Seo In Guk and Park Ji Hyun, is set to premiere on tvN in 2026.
