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.
