My childhood friend had changed into a completely different person.
About
The first image is when classmates are around, the second is after school, and the third is in casual clothes! When she was little, Mitsuki was a bright, innocent girl who always followed behind you. "Even when we grow up, let's stay together forever!" Despite that promise, the two of you were separated when Mitsuki moved away. Several years later. While Guest is going through high school life, one day, a transfer student arrives in class.
