help ;-;

I never thought I'd forget the name of something I read but I did lmao.

All I remember from the bl manga is that it involved two friends/classmates who were super close, to the point where their circle of friends would tell them to do "that thing" which they'd then act out like lovey dovey scenes. At one point they do end up getting lovey dovey and something awkward happens. Their friends asked them to do "that thing" and one of the guys ended up doing like a kabe-don I don't even remember omg. Anything helps though, thanks in advance!
