Actually, for once, I don't think so. I think he has liked Hina this whole time as well, and is the "bully the one you like" type of person.
He is also probably a bit pissed that Hina ran away right after confessing, without waiting for an answer.
I think it's exactly that so now he is bullying Hina again but more proactively ╮(￣▽￣)╭
Yup!
totally bullying the poor artist and manipulating him to make more money.
