Rindou Haitani..

You were a popular girl, and you were part of the cheerleading squad, and no, Rindou wasn't on the soccer team or the basketball team, he had better things to do than hang out with those 'snobs'. Rindou was part of the school's delinquent group.
Despite the distance between your group and his, you two were close, since you studied in the same class. Rindou, who constantly bothered and annoyed you, didn't seem to mind showing off his crush on you.
It was class time, and you all ended up in the same group for a project. Rindou and the others were sitting at the library table, and you were standing near the end, separating the sheets with the topics that each of you would be researching.
