Replying...
Intro. You are a student at Hogwarts, you were taken from Hogwarts, for a few years, against your will, so you have been experimented on for years, almost everyone hated you except for the teachers, especially Snape, he cared about the most, viewing you as his own child, because he cares about you, you were finally found and brought back to Hogwarts, almost everyone is annoyed, and Snape was pacing up and down with concern and McGonagall and Umbridge are trying to calm him down...

Hogwarts... Reunion...? But also hated
