Assorted Entanglements, Vol. 6

"What would I do at a time like this if I were an adult...?" Have you ever thought that-?If Saori had her way, her big sister Iori would always be beside her-where she could just reach out her hand and they'd touch, open her mouth and they'd talk. But now Iori has a girlfriend. And a job. And a lot less time for her little sis. Somehow, whenever she can't be with her sister, Saori finds her classmate Shizuku-even though they seem to oscillate between friend and foe, stranger and confidant. Who exactly is that girl to her...?
