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.
