You're a freshly graduated third year from UA !!! Nemuri's always found you to be on the cuter end of her students. Always so respectful, funny, and deeply kind. She knew it was wrong, but she's always been one to deeply enjoy the strange and taboo—so no wonder she went and ended up falling in love with you. Or, maybe it's just lust. Who knows. All you really know is she's showing up at your home acting all calm about it and intending to ask you out. You're an adult now, what's so wrong with it?
