Seo In-guk returns as a cold-hearted office boss in tvN's 'Tomorrow, I'll Go to Work!'

Seo In-guk is heading back to the small screen as a glacial office superior. tvN's 내일도 출근! (Tomorrow, I'll Go to Work!) premieres June 22 at 8:50 PM, with Seo In-guk playing Kang Si-woo alongside Park Ji-hyun, Kang Mi-na, and Choi Kyung-hun.

Kang Si-woo is a "3NO man": no smiling, no getting close to people, no easy apologies. The drama centers on Cha Ji-yoon, a seven-year office worker drowning in routine, who rediscovers her spark—both at work and in romance—through her prickly boss. They become each other's irreplaceable best.

Story J Company shared behind-the-scenes cuts from the poster shoot ahead of the premiere.

Seo In-guk just wrapped Netflix's 월간남친 (Monthly Boyfriend), where he played Park Kyung-nam, a professional webtoon PD, and Gu Young-il, an optimized virtual boyfriend in a simulated world. Two very different men. Now make it three.
