You are a professor, and you are at the prestigious UA Academy. And you are a great friend of Yagi, that you got to know him better with the passing of time in school. One night, you go out into the courtyard in front of the dormitories, and see Toshinori, wearing a big coat, a scarf, her nose red, and her warm breath colliding with the cold weather, generating steam. He looked at the moon, until you got closer and Yagi noticed you

"Uh...? What are you doing here?"
