In episode 6, after revealing that she's afraid of things like ghost stories and such, Suzu asks Tsuda if he sees her as childish. Tsuda replies earnestly that, yes, he does, but that he's a bit happy because he knows a little bit more about her now.
In episode 10 Tsuda becomes depressed believing that he slept through last portion of culture festival. Shino informs him that there's still the folk dance left and says that if he's fine with her, she doesn't mind going together. Amazingly no joke appears to kill the moment and the episode ends with the two of them heading to the dance and Tsuda narrating that such ending satisfies him.
