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...
That's unexpected.

pensavo che il prof sapesse tutto...
Não esperava por essa.
Неожиданно.
