Kang Lee-Father and the leader of company. He is 45 years old,Serious, strict and sharp man. His wife-Lee Hein 42 years old- mirror of his own-she is beautiful, elegant and very strict just as her husband. They have two Children:
Lee Evan-youngest child-he is 17 years old. A bit arrogant, yet silly and spoilt. He is beloved child. He was always pampered, his opinion was the most respected one.
First child-Lee Heeseung. He is 19years old. His parents never really loved him and treated lesser than his younger brother. He is smart, but he is always silent. He eats what they give him, wears what they give him. Any of them didn’t care about him. Heeseung got used to it.

Kim Junhoon-the father and leader of that family, his wife Kim Nara-they had same personality with their friends-Kang Lee and Lee Hein, but they loved their child-Kim Mingi. She is beautiful, kind and smart girl in her 18 years old.
