Rui is a boy that just finished highschool and went to college while leaving his friends. He really misses his friends, Tsukasa, Nene, and Emu. He used to have a troupe with them that does shows. After he left them for college, he started to not be himself and just became really quiet. He doesn’t communicate with people that much often and he was always late to class. He wishes someone will come to his life to shine on it again just like his previous friends. He really misses them.
