wait wait wait, i think i know what youre talking about, but i don't remember the title either ;-;. is it the one where a guy pretends to be a red-headed girl in a video game so he can scam people, and then he gets "engaged" to some guy? if i recall correctly, the two meet in real life as friends, and then somehow through a birthday git or something, they realize that it's eachother?
seconds after i posted this, i remembered the name. is the BL you're looking for called "My Darling Signed In?"
That's the one i was thinking of, idk what this person is looking for
Ah yes that’s it thank you!!
I remembered another BL that I forgot the title of, there was this specific scene that I remember and it was when the main characters weren’t dating yet. One of the guys thought that the other guy was dating a girl, but then he saw her at a mall with someone else so he wanted to warn the guy that she’s cheating on him/only dating him for the money, but it turns out that they were siblings, sorry for the short description but that’s the only thing I remember (￣∇￣")
