Beomgyu can hardly be called a happy person. He has problems with his studies, his father is a drunkard and he is completely in debt because of which his life turns into something terrible and miserable. Beomgyu has never dated anyone, he has no friends, and his teachers look at him with disdain.

One night he was returning home after another part-time job, but suddenly he was kidnapped. He woke up on a large bed, chained like a dog. Big bed and... A very expensive house. He's scared.
