Need help identifying a long forgotten Yaoi D:

I’ve been trying to find it but google and Yaoi aren’t a match made in heaven. The parts of the story that I remember is that these two guys were roommates in a dorm and basically the uke is hella feminine/androgynous vibes and were hella crushin on each other (ofc). One scene was that the uke got dressed up as a girl at one point and some other guy practically fell over head over heels, after finding out the guy isn’t a girl we was so in denial about it and refused to believe he wasn’t a girl. And another scene was I THINK after the whole friend squad knew about their relationship that they tried “helping” and essentially pushed them into the same shower stall together (like shared gym showers with walls between) and insert fluff scenes, then after the uke ran away in embarrassment bc the guy in denial was actually in a shower stall next to them…and the final scene I remember was that the main lead’s towel fell down and guy in denial basically gawked at his big schlong and contemplated if he was human.

Sorry if that’s a mess it’s been so long and I don’t even know if my memory is even exact to the scenes, but any help/title drops would be really appreciated <3
