Trouble finding titles

Ok because if the entire site crash, I literally lost 8 years of manga collecting and my ENTIRE ‘reading’ list is gone, more than half of my bookmarks are as well.

There’s a specific manga I’m trying to find that I loved that’s still continuing, It’s a BL, the protagonist has pink hair and he basically got to redo his life after thinking he killed his friends in an accident during school when the bus crashed. He’s supposed to act as a villain to the ‘love interest’ who at the start, is his little brother. Who ends up falling for him time after time again. The plot restarts after the protag finishes all the tasks and they move onto another plot but it’s the same guy in the other plot.

It’s one of my favourites but I literally can’t remember the name. I know what it looks like, I know the plot and all of that but I just can’t find it. I can’t find any pictures on my phone either
