Hello! I'm looking for a manga (any pairing is fine; M/M, F/F, M/F) that fits loosely/directly into this:
- Main character's partner cheats on them
- Main character breaks up with partner
- Partner comes crawling back and begs for forgiveness
- I would prefer the main character to be kind of strong-willed
I know this is very specific, so the manga doesn't have to follow this exactly. Thank you so much!! :)
