When seme (or male lead if it's shoujo/josei manga) regretting all the bad thing he has done (especially to his significant other) and trying to make amend of his wrongdoings. Some of the list has uke that is very forgiving, never forgive or died. I don't mind whichever ending, it's just the feeling of regret, from doing bad things or taking things for granted.
Most in the list are yaoi/shounen-ai genre, that's why I used term 'seme'. Feel free to add if you have anything similar in mind.
Yaoi manga where:
1. The seme sacrificed everything for the uke?
2. The seme often gets hurt (emotionally) because the uke doesn't realize that he is hurting him?
3. The uke and seme got into a huge fight then later one of them says sorry?
