I love how suffocating this feels. A very simple and effective animation
I was actually kinda wondering if you'd do an aftermath scene of your previous animation, but I was hoping it wouldn't be as depressing, something like the teacher and the student leading just normal lives afterwards now that the bully had been dealt with but I guess you wanted a more realistic approach?
I have one problem with her death, though. Humans can't actually force themselves to die like that (I assume you either had her asphyxiate to death or drown in her bathtub) as he body would eventually kick into survival mode and she'd reach out for breath. Since you had her go to the tub she could've slit her wrists, that would've actually worked.
Sorry to say, but people drown themselves in the tub all the time.
