What if you live in the same house and go to the same school as your mom's bestfriend's son? Your mom's bestfriend's son who rarely shows emotions in his face and the quietest guy you've ever met. He's unpredictable and confusing because of his always-poker-but-angelic-face. You don't even talk to each other that much, as if you two weren't in the same house.. But will the two of you gonna make progress?
