Kim Euihyun

Characterized by black hair , dark eyes , and a fierce look . As expected, he has a cynical tone and personality . Although he is a foul-mouthed and hands-off person, he is still very affectionate and kind to his younger brother, Kim Eui-young. He actually takes care of himself much better than his father. To Uiyoung, he is like a mother and a father. The father is an example of a bad parent, coming home drinking every day, incurring debts here and there, and frequently assaulting his sons . It seems like if Kim Eui-hyun rebels even once, he gets beaten up a lot. Perhaps that's why Kim Ui-hyeon is said to take his younger brother outside with him whenever possible. Currently , he has a huge amount of debt thanks to his father arbitrarily providing a surety through his own efforts.
