because the sex fells good?? LOL
*feels
I really don't like this story.
All the time the younger guy hated the rapist, but when the rapist tells him, that he loves him he suddenly fells in love too???
Strange story
it's a common theme for yaoi
unless you got stockholm syndrome or something...you don't....it's very traumatizing (understatement) & irl i would castrate rapists, but i am aware of the relationship between fantasy and reality.
do not try to make sense of this, a good portion of yaoi is like this. avoid yaoi if you don't like this type of theme or only go for shounen-ai.
how do you fall in love with your rapist
