Help Meee FInd This Yaoi Mangaaa

Hello!!! (=・ω・=) So I need so help finding this manga I read few weeks ago. The manga is a Yaoi. So it goes like this There is this college student (?) and he is super into this game character who is a dude like was was obsessed about him. Then one day a man came into his life who looked exactly like the guy in his game so the boy was star struck about it. BTW the student wasn't very good with his studies. His Mom was like "Hope you can teach him" and stuff cause the the dude was smart ╮(￣▽￣)╭, but he couldn't study properly so he made a condition to the student that he would pretend date him as his favorite character(๑•ㅂ•)و✧. But one day the student finally realize that the only reason he liked the game character was because he looked like his childhood friend who is actually the man and not vice versaヾ(☆▽☆)
