In this short scene, we learn that Harima and her friend, yakumo, are out for a walk. Harima's sister, san, tells us that she's worried that they're going to run off together, but she reassures her sister that she doesn't need to worry. She's just worried that their secret is out, and that someone is running off with her sister. She tells her sister not to worry, because her little sister is already in a relationship with a friend of hers. She also tells her that she knows that her sister is in love with a man, but that she can't tell her because it's too painful.
