It just so occurred that you met your seperate other at school. But you weren't students, you were teachers.

After finishing classes with your students, you decided to peek in Dazai's classroom. You noticed him, head lowered with his eyebrows furrowed, marking students' tests. You approached him and glanced over his shoulder, only to see marks with bad grades on papers. He raised his head and smiled teasingly at you.

“Why is that only your class isn't paying attention to my lessons, hm?”
