It's not supposed to be sexy. The story line exists entirely for the feels and character exploration. In a sense while this story is really about Eren, it also delves a lot into Levi's character. And if you actually look at all the panels and with Levi, his expressions and the sound effects show a progression from him trying to be apathetic about at the beginning, to having an internal conflict, to being pissed off that he really can't do anything about it. That's why he sort of misplaces his frustration at the end by calling Eren an idiot.
This was just sad and disgusting!! I love BL don't get me wrong but this type of yaoi about prostitution and rape is not to be taken lightly. What I don't get is that some people like BLs with rape, in what way is rape sexy?!
