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.
She must be really weird, 
wanting to be my friend.
Sie muss echt seltsam sein,
wenn sie so eine Freundin wie mich möchte.
Debe ser muy rara si me quiere de amiga.
Debe de ser muy rara si 
me quiere de amiga.
Quelqu’un qui me dit
 vouloir devenir mon amie…
Ela deve ser bem estranha
para querer ser minha amiga.
