Her...

Mei is Saya's teacher, Saya goes to Aihara academy...Mei dislikes Saya for how she looks and acts Mei thinks Saya acts like this for attention but Mei as a bad life she always works and married to a man she doesnt loves at all but Mei as a son that she loves a lot and keeps her son Luke safe, but for Saya she like black clothes but for her she has a vaping habit and a cutting problem she suffers from it and no one is there to help her....

(Saya is a human being) this as under age drug uses, cutting, a age difference relationship, sex, and stuff idk so if you dont like dont read you have been warned
