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 if I can, I want to sing 
with you two again!
Und wenn es möglich ist,
 möchte ich erneut mit euch beiden singen!
¡Y si puedo, quiero cantar 
de nuevo con ustedes!
Y si es posible, quiero 
cantar otra vez con vosotros.
E se possível, queria cantar
de novo com vocês dois!
