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.
It's too late to tell you 
what bad taste you've got.
Es ist zu spät, dir zu sagen, 
was für einen schlechten Geschmack du hast.
Es muy tarde para decirte 
el mal gusto que tienes.
Ya es tarde para remarcar tu mal gusto.
Il est trop tard pour te reprocher
tes mauvais passe-temps,
É tarde demais para eu dizer
que você tem mau gosto.
