Help!!

From chap 22 onwards it’s all about the past and their past relationship.

What are you confused about specifically?

I'm not very good at explaining but I was also a little bit lost :
PAST
Cheol was in a relationship with Minyoung, his uncle wanted to send him study abroad. At the same time, his little brother was being bullied, I don't know if Minyoung did something or was involved in some way, and someone took a weird pic of the little brother and threatened him with make it public. So the little brother wants to flee the country and he wants the uncle to send him instead of Cheol.
So one day, they gather together at home with the uncle to ask him to send the little brother instead of Cheol. But Cheol was like no way, I'm the one going abroad. His father was angry and hit him again. So he runs to Minyoung's house, at that moment Minyoung was not there, so his uncle puts him the bandage and Cheol takes a nap waiting for Minyoung to come home.
He comes home, his uncle tells him he can't do shit to save Cheol because he has no power and no money. Cheol wakes up and then Minyoung tells him he's going to murder his family. So Cheol is angry, even though his family is trash, he doesn't wish for them to disappear. So he returns returns home.
His little brother is frustrated, he sees Cheol coming back, they fight and he pushes him through the balcony.

PRESENT
Miny and Cheol are in a situationship, his brother is still abroad. Cheol grabs courage to tell his father about his divorce. So he goes home, his father is super angry and hits him with a baseball bat. Minyoung was there in the street at the same time stalking, Cheol sees him and gets angry and then he faints. Minyoung takes him home to heal his wounds. Minyoung was son angry that he goes to Cheol's family house and hits the father wounding his ear I think. Then, while Cheol was sleeping and feverish because of his wounds, Minyoung goes see the uncle. The uncle only knew that Cheol's father was wounded, he knew there was something going on between his nephew and Minyoung. In this reunion he understands. Then Minyoung, returns home and sees Cheol sleeping and crying so dreaming about the past maybe....

tell me if it was not that part where you were confused you can ask me a specific question :)
