* Episode 3: Kazehaya telling Sawako how much she inspires him.

* Episode 13:
-->'''Kazehaya:''' There might be times that I won't be able to help you from now on. If I can't, I'm sorry. Kuronuma, I don't think that I'm the type of person you think I am. I'm selfish, I'm really self-centered.
-->'''Sawako:''' That's okay. I don't care if you're selfish or self-centered. You don't have to do anything for me. It's all right.

'''2nd Season and Manga:'''
* Episode 5: Ayane and Chizuru confronting Sawako about her HeroicSelfDeprecation and telling her what she needed to hear the most.
-->'''Ayane:''' You know, Sawako...our first impression of you was gloomy and out of place, too. But now, we know how cute and sweet you are. We love you.

* Episode 9: Sawako finally finds Kazehaya in the classroom and musters enough courage to [[spoiler:confess her love to him.]]
-->'''Sawako:''' My whole life, all I've ever received from other people are apologies. So when you smiled and thanked me that first day, it made me happier than I'd ever been. Despite that, I've been doing the complete opposite of what you've done for me. And that's why, this time...I want to give you more than an apology. Thank you for smiling at me. Thank you for talking to me. Thank you for being nice to me. Thank you for introducing me to so many new feelings...

** Ayane confesses to Pin that she doesn't think of herself as a kind person compared to her friends because of how cunning she can be, and dreads another full-of-himself lecture from a surprisingly quiet Pin, who instead stares at a candy Ayane gave him because he was whining about not getting one after the festival. Then, Pin literally pats Ayane on the head and reassures her that she is kind before walking up the stairs, leaving Ayane (and the readers) speechless that Pin could actually have a PetTheDog moment.
