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.
You've never even heard me play for real.
Ihr habt mich noch nicht mal

Nunca me han escuchado tocar de verdad.
Nunca me habéis escuchado tocar de verdad.
Dire que vous ne m’avez
 jamais écoutée en concert.
Vocês nunca me ouviram tocar para valer.
