If you dont like it dont read it, simple as fuck. Be the author if you have so many complains. Ffs no one is forcing you to read it. Yall are nit picking on a fictional character.
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.
Shoujo and josei series set in the modern day with romance between adults. no teenagers or high schoolers, I'm tired of reading about kids LOL.
college is in a separate list:
