It could happen if when irina enter to the class room and shen she says her name, the students willl ask stuff about her and in one of her answers she will mention issei. One of the students then ask her what's your current relationship with issei. She answers that they are childhood friend and that they have kissed ;0

I love to make stuff out of my head, i hope the author does something like the idea that i provided to you, it would be fun to read.
