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.
But even so, those boring days 
were the most fun I'd ever had.
Dennoch waren diese ruhigen Tage die 
lustigsten, die ich jemals hatte.
Pero aun así, esos aburridos días 
eran más divertidos que nunca.
Pero aun así, esos aburridos días 
eran más divertidos que nunca.
Moi, je profite à fond
 de ces jours
Mas mesmo assim, esses dias chatos
eram mais divertidos do que nunca.
