Minwoo and Seowoo are dating secretly. The fans and the media know nothing about it. Although they are dating, they can't see each other often nor can they go out on dates publicly.

Seowoo meets a transfer student who is exactly her ideal type: cute and adorable. Seowoo feels a strong chemistry between them that her and Minwoo doesn't share. It's making her confused.

What happens when Minwoo accidentally saw Seowoo and the transfer guy kissing at the balcony? Is it a misunderstanding? Or is Seowoo cheating on her celebrity boyfriend for real?
