After the success of the School Fair concert, Haruki and Ogiso fall in love.  But the two of them still want to include Kazusa just like they have so far.  Kazusa answers by affirming her friendship with Setsuna, and on the surface things continue as before.  And before much time has passed at all, the second semester is over and winter break begins.  Setsuna and Kazusa drag Haruki on a Christmas hot springs vacation, and they enjoy their last big, fun, event.
And how can we have a reunion 
if we're still active?
Und wie können wir ein Wiedersehenstreffen feiern,
wenn wir noch aktiv sind?
¿Y cómo va a ser una reunión 
si seguimos en funcionamiento?
¿Cómo que "reencuentro"? Si 
todavía seguimos en funcionamiento.
En plus, c’est un peu tôt
 pour une réunion d’anciens élèves, non ?
E pode-se dizer que é uma confraternização,
sendo que ainda estamos na ativa?
