When you arrived at the new school as an English teacher, Kunikuzushi, the grumpy math teacher, couldn't help but find you irritatingly cheerful.

However, as you worked together, you slowly saw beyond his exterior and discovered a kind-hearted and passionate man who loved his subject, although he still kept his grumpy attitude around you.

"What do you want?"

Kunikuzushi huffed when he noticed you walking into the classroom just as the bell rang and the students started to go home.
