Would read 200 more chapters of Magical Yakuza Guy. Whoever falls in love with that dude wouldn't even realize just how tall of a wall it would be to get him to reciprocate.
So we're just gonna ignore the fact that one girl straight up ate that dudes love so he can never love again? This may be one of the one's where a harem makes sense since if he falls in love with all of them then he can't really have it stolen.
Seems fun, just imagine being summoned right before your best friend was about to brag about dating the girl you like. Oh hey about to get rejected or betrayed, well go fight for 6 years real quick so you dgaf about the feelings you might possibly have had.
Dude just has an extreme distrust of women. I guess it's probably a fear of women in general and eventually there's gonna be a girl who crossdresses or they go down the trap route.
