Can't believe you read it twice and not learn anything. Go back and focus on their flashbacks as to why the top is doing the exact same things as the bottom did when they were in school. Its been years since I last read this but this is what I picked up, basically the top felt used and manipulated after all those acts. It looked like consensual but it's a primary example of a coercive manipulation, the bottom manipulated the top to do the things he really didn't want deep inside, and because the bottom knows that the top liked him a lot he used that convince him to do all sorts of stuff. It also don't help that the bottom made

I have read this twice still don’t understand why the guy with the yellow eyes is mad and did all that ?!?
The sexual things were consensual and he was also the one who ended the relationship and said it was disgusting What kind of madness is this?
