After hanging out with Hyun-woo and Doyoon, Eun-yoo went home that night.
He's a bit tired and didn't want to crumple Doyoon's place so he thanked the male and went back home. It's always like this, whether it's his father's fault or him. The two of them never solve their own problems.
Both running away and coming back after calming down.
Eun-yoo's mother passed away earlier before he reached high school. It must be why his father turned workaholic and became distant from him.
When he was a child, he always wanted his father to give him attention, but after meeting Hyun-woo, everything changed.
Hyun-woo's father was a prodigy in piano. He is a popular pianist that traveled the whole world because of his talented fingers. He first saw Hyun-woo after the funeral of his mother.
