Help me find this manga

I’m trying to find a manga I read a while ago but forgot the name of. It’s about a reverse trap where the guy dresses as a girl and he seduces a girl. I remember the story starting off as the girl meeting her friends and the guy is there. Somehow he seduces her and reveals he is a guy whilst making out with her in the bathroom. Also the characters are either college students or just regular adults, I don’t remember the girl or guy wearing school uniforms.
Please help me find it, I stood up all night looking for it but still couldn’t find it.
