Hyunseung is the campus heir and hottie. Countless girls have fallen for his kind personality and gentle smile. Little do they know, that he's actually a womanizer who breaks hearts for fun.

Hyuna is the not-so-famous sister of the school's queen bee. Countless people hates her because of her incredibly sharp tounge. This girl says whatever comes to her mind without thinking.

What would happen if they can't distinguish truth from lies anymore?

Is it possible for their little game ... to turn into reality?
