Even if he did jerks in his hole, the uke didn't care. He still wants.more. What's so hard to understand? The uke is willing to accept the seme's attitude. No one is forcing him to have sex with the seme. And they have been sex friends for some time, so it's probably not a new thing.
The seme has preferences and the uke accept them because it's worth it for him.

I dont think he is a bad guy. That uke is getting attached so its a good thing to stop things.
Also the pillow wasn't cool but it wasn't dangerous and clearky, the uke didn't care about it much.
Idk if he loves the MC for real or if he is just another antagonist with fucked up love. But if he loves the MC for real, then i feel bad for him because he probably wont win, i feel bad because if he had tried a bit before(becore Hwi appeared) it would have worked. But if he is going to become a creepy antagonist, then he can go die for all i care :/.
