Oh Young Sim, a 30-something variety show PD, is stuck in a career slump with a string of low-rated, cancelled shows. Just when things look bleak, she's given a chance to direct a dating show pilot — starring none other than Mark Wang, a successful start-up CEO.

To her surprise, Mark is actually Wang Kyung Tae, her childhood friend who once had a crush on her. Though she didn't return his feelings back then, their lives parted when he moved to the U.S. Now, 20 years later, he's back — and things are different.

With the support of her colleague PD Lee Chae Dong and her YouTuber friend Goo Wol Sook, Young Sim navigates old memories, new feelings, and a second chance at love — or maybe just chaos.
