Intro

Spring. A lone boy was walking up a slope where cherry blossoms were dancing in the air. Starting today, he would transfer and become a student at this private high school. It wasn't that he had no expectations. However, he didn't plan on having a special youth either. Making friends, studying, doing club activities. Laughing at silly things once in a while. Just a very ordinary high school life. —He thought that would be enough. At least, until this morning.
