He treated MC as a lackey but that's it, he still let others order him around but if it goes too far he'll step right through, I think it's cuz kiyoi thought the guy was a weirdo so he didn't care, not totally excusing him tho kiyoi is a mean guy and that's why MC (I forgot his name) really loves him, so he doesn't mind.
Kiyoi isn't a piece of shit tho, imagine a weirdo like MC being totally being creepy towards you, I would hate it either, so I don't blame kiyoi acting shitty towards MC. Still I want them to end up together, MC is creepy but he knows his boundaries and he literally cut ties with kiyoi for a few years because he thought it was for the better, and kiyoi makes sure to let MC know he's a total weirdo but he still lets him be around him, he likes him but he doesn't show it.
I’m sorry but this is just crap. Being in love with your bully? I can understand that in a sort of fucked up way but that Kiyoi is just a piece of shit, and the other one is so plain it hurts… it’s a fucking stutter! Just get over it!
