Ok... so the gits i get from here is:
Girl likes otaku guy. Otaky guy says her pussy is ugly, girl gets offended by it and insults guy and ruins her reputation by sleeping with the group just to get back at him.
Guy gets traumatized and broken mind that he becomes a hikikomori obsessed in anime girls...

Yup, typical life.

wow

Through heaven and hell, this manga is fucking depressing

How I didn’t met your mother and became an incel: the manga
