Pls help

I'm finding the bl story that I've read since I was in high school and I forgot to save it. That is where the main character regress into high school where the male lead is still alive. So it was like this. The mc likes the male lead older brother— he thought that the older brother was an angel but he doesn't know the he's bullying and threatening the ml. He just found out later on when the ml got into car accident and die. Then later on he got regress and act as the cousin of his youngself and help the younger version of himself to fall inlove with the male lead.


Huhu i don't know it just crossed my mind and I was desperate to find it (っ◞‸◟c)
