Seriously. I mean, I didn't like the manga either (read the first chapter and decided I'd pass on this story), but these comments are toxic! I feel like, instead of calling him "a stinky big slut" or an "onahole," we should try to figure out why the character is acting this way. I feel like his sexual exploits are a cry for help, but most people on here would rather chastise him.
(Skimmed the other chapters to get a better idea). I think we can all agree that the uke's outlook on sex is unhealthy and addictive. But, the boy needs to be understood and helped. Not thrown away and called "a run of the mill whore."
Think of Grease's "There Are Worse Things." ( https://www.youtube.com/watch?v=hGzBZJHhHsc) There's always a story behind actions like these. Maybe it's just the mangaka's fault for not exploring that side of it more.
Anyway, this wasn't so much a response to you fujoshiel but to the entire comments here.
it's 2019. aren't we past the slut shaming? smh grow up.
