The people don't see the point, here we have a handsome teacher, always good in public, act nice to everyone. And then here we have, an adolescent girl who people thought flaunting her cuteness because she an actor. Not to mention I'm sure that bastard of teacher upload that video after heavy editing, which will make the audience think she enjoying it and the one who seduce him. People will scorn her I'm sure of it and she timid one who can't even fight back, I'm afraid that teacher gonna twist the story so hard, hopefully someone will stand for her.
Heck even in real world victim blaming is always real, in my country people often blame the girl who raped instead the rapist because she act suggestive or wear something so sexy. Especially if the rapist is someone who look nice, handsome, and have a good social standing.
