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 that doesn't mean you 
can break the speed limit!
Das heißt nicht, dass du die
 Geschwindigkeitsbegrenzung überschreiten darfst!
¡Pero eso no significa que puedas 
romper el límite de velocidad!
¡Pero eso no significa que puedas ir 
más rápido que el límite de velocidad!
Eh bien, respecte
 les limitations de vitesse !
Mas nem por isso você deve ir
além do limite de velocidade!
