It's not even the fetish part that is the problem, at least imo, like foot fetish? Licking fetish? Cool, who cares tbh, I'm not personally into that but you do you, BUT the biggest issue everyone has with this is the fact that a grown ass person drew two high-schoolers getting down and dirty bruh.. even if you're one of those "it's just a drawing/they're not real" people, can you really say with a straight face that that shit is normal?
Also, god forbid people post their opinions on a shitty manga on a public site available for everyone... we should all just stop commenting at all, what's the point of making a comment?? Mangago should get rid of that function fr.

I actually don't get you people.
If an art of fiction depiction a fetish you're not into, why not just move on and find something else you can enjoy (there are ton of different fetish related stuff on the web (even here) ? Stop acting as if you were forced to read it, you went in by your own will.
You need to know and understand that not everything is made for YOU or will be YOU-friendly, just move on.
