I don't know about a manga, but a manhwa kinda fits this plot. It's called "Again"

Whoa thank you so much! It is this one!!!
It was a bl story. Main guy loved this guy and they were somewhat together. but someone threw acid on him. So the guy dipped him because he was ugly now? So he cut his wrist and died. Magically time turned back and went for the other guy who actually loved him for a very long time?
