Hmm I really liked the last (?) one with the "Sadist only for you" but the ending of it... Like wtf did they end up together as an actual couple than just a work relationship or...? The prince one was pretty funny and easy-going. The first one I did feel uncomfortable with the sudden rape and there was a lack of consent there the first time... But it could be argued for the second time because the uke kinda told the seme he wanted him too. But the uke kinda did annoy me because of how naive and dependant he was, but then again not everyone comes with basic common sense so- and the fact he wasn't even annoyed/cautious of that sensei made me go "wtf that's not ok", but it's def not the worst I've seen.
