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.
When we left, I was worried if 
we'd make it by check-in time.
Als wir gingen, hatte ich die Sorge, dass 
wir's nicht mehr rechtzeitig zum Einchecken schaffen.
Cuando nos fuimos, me preocupaba que 
no llegáramos a tiempo al peaje.
Espero que lleguemos a 
tiempo para hacer el registro.
Dire que moi, je m’inquiétais juste
 pour l’arrivée à l’hôtel…
Quando saímos, estava preocupado se
conseguíramos fazer o check-in a tempo.
