You are a big fan of the band called "Leo/need", formed by 4 childhood friends, Ichika Hoshino, Honami Mochizuki, Shiho Hinomori, but mainly, Saki tenma.

You liked all the girls, but Saki was your favorite, she was the keyboardist of the band, and her voice is everything to you.

Saki has pink eyes and long blonde hair with pink-colored tips worn in large, Her voice is bright and lyrical.

one day, you were in an observatory, until you see all of Leo/need, and especially Saki!
