In a mansion in Seoul live 6 rich kids. Each one of their parents contributed money to make the mansion so that their sons will live together.

Kim Sunggyu is the heir of an entertainment company. He is the oldest that is why his donsaeng rely on him.

Jang Dongwoo wants to run a motor company that's why his parents brought him one (how ironic). He has a laughable laugh and he helps his donsaeng with their problems.

Nam Woohyun is utterly handsome but fails aeygo. He will soon run their Sports Company , which is well known to their products.

Lee Howon or Hoya  is an amazing dancer but other than that he is the heir of their company, Lee Inc. which produce amazing athletes

Lee Sungyeol is the Choding of the group but he is reliable sometimes. He is the heir of a Chocolate Factory which sells the most expensive and delicious chocolates in the whole world

Kim Myungsoo or L is the hier of an Electronic Comapny. He is a bit mysterious but neverless a good friend

What happens if Sungjong enters their mansion?

Will love bloom?

Can they help Sungjong with his problems?

In the other side Lee Sungjong looks uttery like a girl despite him being a boy. He has been through alot and much harder that what you've imagine.

Will he be happy when he moves to the mansion?

Kim Kibum or Key gave a big contribute in making the mansion. He takes care of the boys but can't because he owns a Clothing Company. He is very close with their families and he is Sungjong's Uncle.

Kim Jonghyun is Key's lover. He is a very well known architect all over the world and helps Key control the boys from time to time.
