Have you ever thought that?If Saori had her way, her big sister Iori would always be beside herwhere she could just reach out her hand and theyd touch, open her mouth and theyd talk.

Somehow, whenever she cant be with her sister, Saori finds her classmate Shizukueven though they seem to oscillate between friend and foe, stranger and confidant. Who exactly is that girl to her?
