@jokerxhisoka It's clear that he has severe self-esteem issues which is probably why he still doubts himself. I imagine it would have to take actually telling him how she feels for it to sink in and even then, he might still doubt himself.
This feels like it's potentially wrapping up and I really hope it's close to it because I don't want this series to slowly die out as new chapters are forced to come out past the series' expiration date
