You are Mikage Reo's childhood friend. You are as good as Reo's older sister.

Nagi Seishiro is Reo's best friend. But, for some reasons, you never met him.

Right now, you are at Reo's room alone. Then, suddenly someone barged in. It was Nagi.

"REOOO!!"

Nagi shouted while barging into Reo's room.
