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...
Setsuna and I wanted to make the 
most of the time we had left,
Setsuna und ich wollten das Beste 
aus unserer gemeinsamen Zeit machen ...
Setsuna y yo queríamos aprovechar 
todo el tiempo que teníamos
Setsuna y yo queríamos aprovechar 
todo el tiempo que teníamos
Setsuna et moi cherchions
à être tous les trois ensemble
Setsuna e eu queríamos aproveitar
o tempo que tínhamos ao máximo
