I would have really preferred if he acted more professionally. I'm not exactly sure how one should best handle the bath situation. Tbh that is 100% sexual harassment if the gender is reversed, but I think he can at least firmly tell her to stop. She might back off if she can tell he's really serious. As for the sleeping thing, if she's really scared, he could have just sit beside her till she's asleep. I want the story to advance, but I'd prefer it if the student-teacher relationship is treated a bit more realistically. Obviously the series has ended but I just wanted to write down my thoughts
