No he's not.
Their relantionship is consensual and he shows that he cares about the uke ALL the time. They have a somewhat dom/sub relantionship, so far he seems to know exactly which lines he can cross and which he doesn't. They both also mock eachother, damn, he even said he would buy him a Seoha sized dildo next time bc this one was too small.
They have good chemistry, good relantionship, they be roomies and buddies bruh. They are wholesome on their own way, it's just not a sweet honey cheesecake way, more like a freaky kinky and funny way.
At the very least this is how I see them and apparently most ppl as well, based on like to dislike ratio.
Also, he's fucking hot.

Re-read, mah dear cause I never put words in your mouth and I simply told you how most people see their relantionship, me included.
Also, it's your opnion and your right to think he's toxic and it's our opnion and our right to think that he gives the uke exactly what he wants/needs (hardcore sex and a free bullshit friendship).
Sidenote: Not everyone is all fluffy in a relantionship but, that doesn't always necessarely means they are therefore toxic. Or something like that.
Anyways, I'm gonna go cause I have a bunch of things to read now, bye ヾ(❀╹◡╹)ノ~
i hate that piece of shit roommate.
