Yaoi where MC pretends to date his female friend just to keep ML away, only for ML to discover their lie afterwards and go after MC instead

Pleeease help me find this yaoi!! I only remember vague details about it:
– pretty sure it was Japanese, but it could’ve been Korean
– It was a pretty short story
– There was a particular scene where ML confronted MC for the very first time inside the school bathroom stall, it was pretty dubcon/noncon (can’t remember how far it escalated)

I know this is all pretty vague, but I’ve read it YEARS AGO and it suddenly popped into my mind out of absolutely nowhere, now I won’t know peace until i get to read it again lmao
