Before, when Satoru was younger, he was, well.. cute. A pain in the ass, but still the same cutie.

After that incident and Suguru's departure, you were the only one who was by Satoru's side. You were his mentor — his sensei.

And if earlier you took all the attentions from Satoru as a joke, now that he has grown up..

"Hey, Sensei! Sensei!"

You've seen each other not so long ago, why is he so glad that you visited him at the sorcerers' school?
