OI , dat boi supposedly went on this half-assed, or 200% assed, date for her sake. But in the end, all he did was push all of his insecurities and issues on her. Shes not really resolved at all.
This isn't an issue with the manga tho, honestly how old is he supposed to be. People much older than him are not emotionally mature enough to handle those time of issues any better than he did. Lets hope the hero learns some more empathy.
