Looking For Yaoi Manga

Hello PLEASE HELP!! I read this manga a while ago i cant for the life of me remember the name. Does anyone have a clue? The manga is about a college student who is secretly an otaku but pretend to be stylish and cool so he can have cool friends and fit in. He starts seeing this guy who dresses lame like him and the end up having sex and when he goes back to tell his cool friends about it, it turn out one of the cool guys was actually his fuck buddy but the mc hasn’t realized it because he dresses so differently.

Anyone know the name of the manga where the seme travels from the past to the future and he’s an Italian gangster? He ends up staying with a guy and then ends up loving him and staying with him forever?

Lol that’s what I sorta remember but if you know it pls tell me!

Thanks :)
