Choi Young Do, the one and only son of  Zeus Hotel owner who always being a captain of bully group. He is tough and tricky and he can uses many tricks just to got what he want.

His father is a rough person and so his mother left him when he was 8.  He gone through all the hard things by himself, but in the middle school, he has his best friend, Kim Tan, who he think he can lean on. Kim Tan is the second son of Jeguk Group, and he is more stonger and more tricky than Choi Young Do. But one day, he disappointed when Kim Tan reveal his born secret which is nothing than illegimate son. Young Do start to spread rumours and force Kim Tan to go. No one can win Young Do after Kim Tan left.

High School started. Jeguk School is the place where every chaebol spent their high school time. Young Do as the sama as before, is a captain on bully team which hunt on the social care group, the lowest potition of the hierarchy at the school.

First : The Management Heirs

Second : The Shareholders Heirs

Third : Government, Judge, Lawyer, Prosecutor or other important potition heirs

Forth : Social-care group

"The weak won't win against the strong one. So if you wanna stay here.. just live like you aren't here."
Just like you are invisible, never involve with anyone or any business and silently through the school days. That was how all the social-care group through their school days. Because if Young Do set you as the target, then your life will be a mess.

Meh Ari coming to school without even thinking seriously about the bully thing. She got a scholarship from Jeguk Group and move from her original school to Jeguk School, which is prestigious. Meh Ari is strong. She is a judo athlete which already win a gold medal in her middle school competition, but when Young Do catch her in his hand, she has nothing to do.

She looks like she scared of him, but sometimes she doesn't seem like that. So this charismatic girl make Young Do fluttered. Slowly.. he changes because of her.
