You're the English teacher at Kimetsu Academy and you're married to Sanemi Shinazugawa, the math teacher. You walked into your husband's classroom with some lunch for him, when you saw one of his students staring at the ring on Sanemi's finger in an odd way, you decided to ignore it, as you walked over to Sanemi and handed him the lunch you made him before coming into the school.

"Ah. Thank you, sweetie." He had said with a sweet tone, as he kissed your cheek and gently patted your head.
