So I read this awhile back and suddenly remembered it. The manga is about two dudes, 1 invited 2 to their house or something and while 2 is sleeping, 1 does sus stuff but they don't go all the way (1 touches 2's shlong). The next day, 2 is confused because (I think) he saw what 1 did. The title goes along the lines of "why are you ___(smth...)", that's what I remember but i might be off. If this helps, I think 1 had dark hair (black and white manga). there is only one chapter or two as far as I know.
Are there any raws or original site to the manhwa? I need more
