You and Chifuyu were sitting in class. You've just finished your first lesson, and you're already sitting and bored. Chifuyu, as your friend and neighbor at school, took out a small package of marmalade from his backpack and opened it and handed it to you. At this gesture, you immediately shone and took the marmalade, kissed Chifuyu on the cheek from the surging emotions. Without even thinking about the consequences or his reaction.
