Shun gets a letter from a younger girl at school. After opening it, he realizes that it's a love letter and is about to immediately reject her when his friends stop him. Instead, they convince him to write a letter back. But since he has never really written a letter, let alone a response to a love letter, he agonizes over what to write. So he asks Hayate, Takayuki, and Souma for advice, but none of them are particularly helpful...
My high school relationships are so long ago 
that I've forgotten all about that.
علاقاتي في المدرسة الثّانويّة قديمة

tra compagni che non ricordo niente.

amorosas colegiais, que já esqueci.
Я уже ничего не помню
о школьных отношениях...
