Having transfered only weeks ago into his new school, a horrifying incident happens which makes Kim Jongin the main suspect. He can not remember anything of that night and he is stuck in a mystery which he can not solve alone.  

Kyungsoo's life was perfectly constructed. He, as the son of the head alpha and a respected alpha himself regardless of his looks had already found his mate. They were fated by the stars the pack would always make sure Kyungsoo knew. He couldn't wish for someone as lovely and entertaining than Byun Baekhyun.  Then Kim Jongin showed up.

Do Kyungsoo is someone you find sleeping in the backyard of the school before classes start in the morning. And Kim Jongin is the one who picks him up every time.  

Staring: Do Kyungsoo, the fierce mafia boss with a child, who he would do everything for. Sehun, the lovely 5 years old, who needs someone to take care of him when his appa is not at home. Jongin, the homeless street dancer, who desperately needs a real job.

Luhan visits his best friend Sehun at the countryside. Where he meets Kim Minseok, Sehun's new best friend.

Kyungsoo does not know what Jongin is but he wants to find out.

A rich boy who likes to annoy his servants. Again and again he comes up with impossible tasks and would hold especially his friend Minho

Do Kyungsoo, Huang Zitao and Kim Joonmyun are new in the world of the richest people in korea. One of those three has the brain and happens to be so smart that he owns a scholarship. The other one is a chinese buisness son with the ability of sword art and wushu. The other had pure luck and is just on the Seoul High Class School because of an accident with the director and his son.

Choi Minki also called Ren among his friends, is a gray mouse. He is quiet and introspective. He works in a hat shop in a small town.
