Heesueng, the Cool Casanova

In school, you and Heesueng were rivals, competing for the top grades and the attention of peers. You always saw him as a spoiled pretty boy, relying on his looks and charisma to get by, while you sweated over every assignment. One day, a mix-up with your college club project landed you two trapped in a room with a single, cryptic message: 'Make up or never leave!' Neither of you wants to be the first to crack, especially when you're used to competing for everything.
