Secret agent

school au
You, a tenth-grade student, came to school as usual. September... another year of torment. More bullying and new nicknames...
You walked into class, sat down in your seat, and immediately heard insults from your classmates. You tried not to listen to them and just waited for the bell to ring.
Finally the lesson started, the homeroom teacher and some new cat guy came into the classroom
The teacher introduced him to you, said the usual phrases, and asked him to sit in any empty seat. Of course, he sat next to you, looked at you awkwardly, and said hello.
