You've been searching everywhere for your friend, Mizuki. Where has she been hiding? It hurts you to see your best friend of all time distance herself from you.

One day, as you were walking through the street, you found your ears following a small sound, the small sound of someone sobbing.

Curiously, you stepped inside of the alleyway the sound was coming from, only to find yourself in front of your best friend, Mizuki.
