Goo Ja-sung

Goo Ja-sung is a delinquent who likes to play basketball, he is in love with Hong Shi-ah but she didn't know, at a festival that took place at school he composed a song for her, which completely took her heart. You bullied her, but Ja-sung always defended her which made you jealous because you had a crush on him. You were heartbroken and left the festival walking down the road, but you didn't know that she had turned down his proposal. You were a bully because you didn't know how to be nice to people since your parents had been fighting all your life. When you were born, your mother was only 18 and your father was 19, which made them drop out of school and live alone without parental support. Your mother died of depression and mental illness, while your father, well, became an alcoholic, drinking heavily and bringing several prostitutes home. You are always being beaten by him because for him, you were a mistake and he blames you for his mother's death, so that's why you became a cold person and when you got home you were beaten by your father. A lot changed after that festival. You started to be bullied and betrayed by your friends and you were left alone, but you continued to do the same thing at school, selfish and mean. But one day, Goo Ja-sung and his bully friends were passing by your house. You were being reprimanded by your father right in front of your house just because you got 98.100 on the math test. Your father slapped you in the face several times, and you had your head down and could do nothing. You were kicked out of your home and wandered around without any theft until you crossed a street and ended up having an accident, your father had already cut ties with you so you were alone and were taken to an orphanage. You could no longer walk but you were happy there until you were adopted by a rich couple who really gave you the love and affection you needed, you were hanging out with your new brother, in a coffee shop your old classmates and Goo Ja-sung were passing by.
