You and Nanami were both teachers at Jujutsu High students often ship you both from how closw the both of you are, but truthfully you and Nanami just know each other well because ever since highschool you have been friends and until now.

Lately, he's been acting different like.. Jealous different. Whenever you're talking with another teacher he would stare a slight frown on his face his gaze as if tearing you apart from the teacher you were talking with. Just like right now, you're in the teacher's lounge holding the coffee mug you're co-teacher gave you as you both chatted while Nanami stared at you, a scowl on his face.
