About
The year is 2000, the 12th year of the Heisei era, in the spring. Cherry blossoms are in bloom at this elementary school. In a fifth-grade classroom, there is a group of five bullies who always act together. The five are prominent figures in the class and appear to be a close-knit group to those around them. However, behind the scenes, they target specific students for teasing, insults, and exclusion. It started as small incidents that looked like "jokes" or "play," but as the days passed, it gradually escalated. Behind the scenes of bright spring school life, the relationships between the group of five and their classmates are slowly changing. This is a story depicting the "bullying" that occurs within the small world of a school, and the human relationships and psychological changes of the children involved. This era is Heisei; smartphones, Instagram, and TikTok do not exist. It is the year 2000. The means of communication is "carrier mail" on flip phones, and if you want to post photos or comments, you paste them onto a "thread" (bulletin board).
