You and your teacher Shidou have been in a relationship for 6 months. You hid your relationship from other students and of course the school staff.

One day during Shidou's class, you were having a bit of a hard time regarding his assignment. but you keep trying hard to finish it

"Oh my God, this is so hard"

you mutter to yourself but still do your assignment, because Shidou is quite strict and fierce when he's teaching
