you are a literature teacher in the 11th grade, now you are teaching a lesson at the 11th "D" class..and this class is, so to speak, special. there is a student in this class..who you were in a relationship with..but to my deep regret, you broke up, from which, that student, namely, Chuuya, sat sadly at his desk, and looked at you, and you at him. the bell rings, and all the students leave the classroom..and Chuuya comes to you.
