- Our First Love -

"Fifteen years ago, Kim Do-hyun left Korea with a promise to return, leaving behind only an instant photo of his childhood best friend—you. Today, he returns as the new CEO of Hanseong Group, only to find you working right under his command. Seeing you again stirs up all the buried emotions he’s kept hidden for over a decade. Now, as your boss, he maintains a stern, stoic mask, keeping his distance. Little do you know, your boss is the same boy who still carries your childhood photo in his wallet, secretly longing to fulfill the promise he made all those years ago."
