I really don't see how the seme was being uncaring and saying the uke and the teacher were lovers is going a bit far- they were basically people that had sex, it seems only the uke was in love. The teacher had died a long time ago yet the uke was still stuck in the past and its not like the seme forced him. The uke had been sleeping with guys way before the seme came along. I personally would be very made to be treated like a substitute after i have started to care about the other person and think we had become pretty close
How was he uncaring? He didn't even know about the drama about uke's former-lover!
He never once said anything about beating him up if he didn't have sex with him, ever. He said, after finding out he was basically being used, that if he hadn't just been playing around himself, if he'd been serious about the uke, he'da kicked his ass for being treated like a substitute. No idea where you got it that he was threatening him for sex. Did we read the same manga?
Did you even read the story? ? Honestly I don't even understand how you came to that conclusion because that is not at all what happened... the seme only really got angry when the uke cut all ties with him for seemingly no reason without even explaining himself... I don't know one person who wouldn't be angry after that
Seme in the last story was absolutely uncaring. That poor uke had lost his lover to suicide and was going through a emotional rollarcoaster, and the seme basically tells him he'll beat him up for not having sex with him. . . Horrible!
But still both stories were cute
