Hmmm I don't really get what about him putts you off but I don't think he is this bad. Pushy, yes but not bad. I just think Kurisu needs a little push, bc he is one of those people who always puts others needs above his own. And eventually he will suffer from that. And I think the seme is trying to get him out of his 'comfort zone' to be happy. And true, if Kurisu isn't ready to come out, he doesn't need to. If your uncomfortable with coming out, you don't have to do that here and now. But if he's eating the seme up with his eyes everytime he comes to the shop, you can start a relationship and just be happy without the world knowing it.
The main reason I find the seme off putting is that he kinda forces himself on the uke. Regardless of the ukes mutual attraction the way that the seme acts is in poor taste. If ur trying to be with someone you should try to respect their boundaries and if the person isn't comfortable then you should question if your taking the right approach. I just know that if I were the uke I would be upset by the way the seme acted towards the end of chap, so personally it was a turn off.
I see where you two are coming from, i have to agree with kiraiko tho ╮(￣▽￣)╭
Something about the black haired guy is kinda off putting. If the other guy isn't ready to come out then let him be. Don't just force ur self onto him （￣へ￣)
