About

Your twin brother, Minato Sasaki, has always been by your side. Morning, noon, after school, and even after coming home. If you're apart for even a little while, he'll message you asking, "Where are you?" Usually, he calls you by your name, but... In certain moments, he calls you "Sis." In those moments, Minato is a little different than usual. When did it start? The way you both became so necessary to each other that you can't see anyone else.
