OMG YESS THANK YOU QAQ
I don't really remember it well anymore but it was pretty cute. A manga about a pretty guy that was known as the schools Madonna and had alot of guys that liked him. The protagonist happened to see him supposedly kiss a teacher but the kiss actually didn't happen. They meet and the Madonna guy starts hanging out with the protag and boom they fall in love.
