male lead is so obviously hesitant at first, it feels a bit rapey to me, even though he was reacting once properly pushed. Reading the text, he's not in Love with the girl? Saying "sex comes first" and possibly be in love with the teacher. That half sentence "not when the girl I like" after all.
But I don't know. This is obviously just a fantasy and I'm overthinking it, totally, don't let it bother you.
