"Right now, I don't know if I want to kiss you or shove you off a bridge." "Can I pick?" 

Wooyoung is a bright, cheerful college student. He works hard, plays hard, and lives life to the fullest. And then, he gets a new roommate - San. There's not much he knows about San - truth be told, there's not much anyone knows about San. San can see the future of anyone he touches, and this drives him insane. Nobody around him can be trusted, so he isolates himself from the world. They have the same intentions, really: do what's right. But when the two of them meet, they are anything but a perfect fit.

Wooyoung wants to show San a happy world, and San just wants to stay away from the world. But at the same time, San finds himself following Wooyoung, the sun in his cloudy sky. And maybe Wooyoung can light up the clouds, and be the silver lining in San's life.
