Isn't it totally appropriate for the student rep to be asked to help another student? And isn't it totally appropriate for the teacher to write a rec to a student who does something extra like actually go to the person's house?
Is a teacher responsibility first, but she gave up... Also, it would be totally fine if the deal is settled now, after all, she is now attending class, her responsibility ends there. But somehow I feel like the teacher won't keep her part of the deal if the lonely girl decides to stop coming.
Okay, where is this coming from now? The teacher didn't blackmail her at all. She just offered her a deal that has no repercussions if she doesn't agree on it.
Maybe not blackmailing per se, but I'd say the way she's drawn in this last shot and the fact she knows MC's weakness sounds exactly as if she was using it against her and pressuring her to do it, because she knows she won't refuse her offer. In short, she just gave bad vibes to me.
It'd be coercion. It's not quite as bad as blackmail but it's still not exactly good. Blackmail is actively using threats of revealing something to goad someone into doing what you want but coercion would just be convincing someone to do something they probably wouldn't do on their own.
I'm already on edge with this one but I'll give it a chance and see if it manages to successfully walk the knife edge of creepiness that most blackmail themed plots fall right off of.
