There is one house, on one lane, in one neighbourhood that no one dares to enter. One young man lives there. His name: Henry Lau.

Henry Lau is a young man with mental problems. He is loving, kind and sweet. But when someone he loves gets too close to him, he snaps. Some say it's the medication he's on. Others say it's the way he was brought up. But all the doctors know is that it can't be controlled... Or can it?

A new doctor has arrived on the scene. Kim Kibum.

Maybe he can figure out what's going through Henry's mind...
