I can't speak for anyone else, but frankly I don't particularly give a fuck whether or not it's yuri. The yuri is fine. What bothers me about this chapter, in particular, is the everything else that's going on in it.
Stalking, home invasion, harassment, manipulation, and potentially confinement (she was picked up and carried off, and she didn't come back to the school for a full week). The worst part is that the teacher actually reached out for help, and they made a brief, half-hearted attempt before going "welp, I did all I can" and leaving her out to dry.
