Guy(A)suspects he's gay. Tells a friend(B). They go to a gay bar. A goes somewhere and when he comes back, he finds B with some guys. Guys tell him that he's with them willingly. A is like "okay" but goes back cuz he thinks they're lying. Asks those guys B's name, they are unable to answer

I read it long ago on mangarock. It was a straight romance manga(?). Coloured. I think it was actually manhua tho.
Girl was a tomboy and she got engaged(?,I don't remember) to a long white haired guy who was a little feminine. Towards the end, the guy was insecure cuz he wasn't masculine.. and they shared words and happy ending!

I think the art was similar to those of cultivation manhuas.
