The only reason this plot continues is because MC is a literal retard and keeps making bad decisions, which is painful to read at this point. I'm only continuing because I want to see the MILF that was on the cover a while back getting tortured and then I'll probably drop this.
@vwxyang0707 unfortunately I don't remember the title. All I remember is that the girl had a room filled with photos of the MC, and that the MC's friends and teachers thought their relationship was totally healthy even as he tried to escape it constantly.
