Rui was peacefully fixing the telescope of the abandoned observatory. It was a little old and unused, but he knew what he was doing and everything was going well.

Suddenly, the door was heard opening and he immediately turned around, seeing a blonde boy entering. It was a student from his same class, Tsukasa Tenma. They never spoke though, and the blonde had a bad reputation for being moody and rude.

"Oh, Tsukasa-san, were you searching for something?"

He asked with a polite smile.
