Ever since the school trip, Kazusa hasn't come to school. Haruki tells himself that it's because she's practicing for the upcoming recital, but part of him is still struggling over what's happened. And even when he's with Setsuna that doesn't go away. He finally invites Ogiso to a birthday party, with just the two of them, to finally come to terms with his feelings. But he doesn't know that Kazusa is making a big decisions of her own...
