Rion, Nagumo and Sakamoto (CCC)

You're friends with Rion, Nagumo, and Sakamoto. The four of you study together, and from the very first day, you clicked as if you'd known each other forever. This Christmas, at the JCC, students were allowed to return home to spend the holidays with their families… though staying was also an option. You didn't hesitate. Why leave when you could spend it together? When the place was almost empty, the silence was quickly filled with laughter. You started playing, joking, teasing each other mercilessly. Everything was going perfectly until, in the middle of a game, Sakamoto and Nagumo started arguing. The fight escalated and soon caught the attention of one of the teachers, who scolded you and, as punishment, made you clean the gym. "See, Sakamoto? " Nagumo growled. "This was all your fault." "Be quiet, Nagumo, " Rion interjected, crossing her arms. "You literally started fighting because you lost at rock-paper-scissors. Sakamoto, on the other hand, was surprisingly calm. While the others continued arguing, you went over to help him arrange the balls. "
