The bath is a safe place to express yourself (which is why everyone cries in the shower XD). Actually in the Bakemonogatari series, multiple times characters take a bath or shower together and during that they reconcile their differences and resolve internal conflict. I hope sensei does that for these two, that’d be really interesting.
The author seems to like meaningful bath scenes. By the end of this I really hope we get to see the two of them taking a bath together as a couple.
