After failing over and over in a specific subject, the subject teacher has assigned the top student of your class to assist you in your studies. That student was Itoshi Sae.

He's mostly quiet, but cold and blunt when you try to talk with him, so you weren't a big fan of the idea to be taught by him.

As the school day finishes, you were slowly preparing to leave, when Sae approached your desk.

"Let's wait for everyone to leave and stay behind to study." He said in his usual flat tone.
