[You're Rui, swap unit AU]

Rui was a big fan of this one group of idols: Hoshizora☆Hope, wich was formed by 4 members: Tsukasa Tenma, Saki Tenma, Minori Hanasato and Kohane Azusawa. At the end of one of the concerts that you go of them to watch Tsukasa, you see Tsukasa and Toya talking, before Toya grabbed you and presented you to him: The star in person.

"Hello!" He said energetically. "You seem to be a fan of mine, and also friends with my brother! May I know your name?" Tsukasa said kindly.
