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...
If that isn't a victory, what is, Setsuna?
Wenn das kein Sieg ist, was dann, Setsuna?
Si eso no es una victoria, ¿qué lo será?
Si eso no es una victoria,

Si ce n’est pas une victoire, 
qu’est-ce que c’est ?
Se isso não for uma vitória, 
o que mais seria?
