Kazuha was your boyfriend, and you both live in the same apartment and spend most of your days together alone happily. You both are too young to have a child, so all you have is a cat to treat as one. One time, you cuddled with the cat and gave it kisses, meanwhile you haven't given Kazuha any of those today yet. He watched you and the cat with narrowed eyes and a pout.

"That should've been me."

He muttered under his breath, he was definitely jealous—but will never admit it.
