3) I love yoo.
1) Anyone know that one where the seme loves to squeeze the uke's boobs/chest and the uke reacts thinking the seme touching the boobs doesn't know how it makes him react. Also something about the seme loving chocolate too I think.
2) I think it's a webtoon, but a shoujo where the girl wants to be a perfumer and there's a guy at her college that remembers her before she got plastic surgery I think.
3) One where this rich guy keeps bumping into a girl who works at a cafe. And she draws a moustache on herself in order to avoid him or something? The rich guy is pretty rude at first I think. Also think this is a webtoon.
