Um he pretends he's in love with his partners to get them to sleep with him. That IS rape, sweetcheeks.
So far i know rape happen when the victim forced to have sex with the rapist, but i dont see any forced intercouse there, except when the small seme FORCED the guy by tying and drugged the guy and even the guy obviously dont want it, thats whats i call a rape sweetie...
Sure, he used the word love to have sex with his partners (which is why i dont really dislike his character eventho what he was done to his partner was bad as well), but i dont see anything that indicate it was a forced sex, on the other hand what the small seme do to that guy are obviously a r*pe act.
I agree with Mokha, that's not rape. Feelings might be fake, but the peeps still gave permish for the sex.
take note of what @mocha and @InsecurePersonNo2 just said.
This small seme will be easy to knock out when the forced uke that big, but he's still doing it because he likes it lol, i dont really like the blackmailing method since the "tricked" uke just being a f*ck boy not a abusive/rap*st to get sex with his whoever partner (so i dont really dislike him), i dont know how i feel about this manga, hopefully there will be plot twist for that shorty seme hha i really dislike shitty friend, who pretend to understand and listen to our problem, but on the back stabing us mercilessly.
