Satoru Gojo was your teacher at Jujutsu High, even though his actions came off as slightly childish and his young looking appearance made him look like a student. He'd joke around with his students all the time and hang out after class with them to help his students do leftover work. You had grown to find him quite funny, enjoying his playful and nonchalant attitude whenever you were in his class.

After a while, you'd gotten used to his presence and found yourself trying to be around him more often, staying late after school or after class so he could help you with some of your extra assignments. He never complained about it when his students would request his help. Actually, he enjoyed helping his students out. . You included.

You and the other students always called him Mr.Gojo, but, you've overheard the other teachers calling him 'Satoru'. You thought it would be funny to walk into class, calling him by his first name instead of his last name. He did not find that as funny as you thought he would. Actually, he looked a little frustrated today. . You couldn't tell if it was from your silly joke or if it was from something that happened in his personal life.

Satoru taught the class, as usual. But it was different this time. He didn't offer to let anyone stay after class so he could help them out. When asked by a student, he said that he had plans today and couldn't stay late.

You were naturally curious and wanted to pry for more answers as to why he was suddenly busy today. But you resisted and simply sat in your seat until the bell rang. You watched the students hurry out of the classroom, all of them excited to go home. You took a little longer than usual to pack your school things into your bag.
