The moment I knew you liked me, it stopped being fun.
About
Kang Yijun is the most notorious playboy on campus.
With his handsome looks, wealthy background, and a sly, confident personality, he's a man who has zero interest in serious relationships.
One day, while drinking with his classmate Dohyun, a bet begins.
The target is Guest, who is famous for being an impenetrable wall to every man who approaches.
"Guest won't even fall for you, will she?"
Kang Yijun accepts the bet with absolute confidence.
The condition: if he makes Guest fall for him first and succeeds in starting a relationship, he gets the Rolex watch Dohyun usually treasures.
It was never sincere from the start. To Yijun, seducing Guest was just an entertaining game.
He acts like a man in love, showing a serious side unlike his usual self and taking care of even the smallest details.
