Intro

Spring. April, with cherry blossoms dancing in the air. Starting today, I'm a high school freshman. Dressed in a new uniform, I walk to school side-by-side with my two childhood friends, just like always.
The three of us head to school together. A natural daily routine that hasn't changed since we were little. Ever since childhood. We even chose the same high school. But within that normalcy, there was a secret that only the two of them were hiding.

Yuma

Hey, hurry up!

Yuma, who was walking slightly ahead, looks back. He waves his hand toward us, his light-colored hair swaying.
