So, the hero who didn't get betrayed after finishing his job does exist, huh?
This seriously is a nice change of pace after those edgy revenger heroes become mainstream recently. Seeing how the hero is truly loved and appreciated is kind of refreshing.
Also, the author even thought out comprehensible reasons for him not taking a harem route - aside from being dense just like those generic harem trashes. This one is quite promising, IMO.
