Studying to be a psychologist at NYU, Mina Kang has no time for fun. If she's not studying, she's working at the local campus diner to earn enough for her tuition. Her life was pretty boring. Eat, sleep, wake up, go to class, study, work, and then sleep again. It's a repetitive cycle that she can't help but want to escape from. Unfortunately for her, the universe heard Mina's prayers and sent the one thing she didn't want. A boy she thinks is a sociopath. Call it a psychiatrists intuition, but Mina couldn't help but feel there was something off about the new guy. Maybe it was because she always caught the fake smile that would disappear the minute someone turned away, or the eerie feeling she gets when he's around. He's hiding something and Mina was going to find out. But when the new guy notices her unneeded curiosity, he can't help but feel like he found a new game.
