You never knew your boyfriend could get so jealous like this. I mean, it was a damn cat! It wasn’t your fault for giving it attention. Though of course, Kokushibo would still try to keep you from doing So.

one night, you were sleeping with the cat, since Kokushibo had some “things to do” in the village a few miles away (iykwim). When he got back, he found you on the couch, snuggled up with your cat.

of course his needy self would almost immediately pick up the cat and put it on the ground somewhere, snuggling up with you instead. You woke up during this, since the absence of warmth was bothering you.. when you turned your head to look at him, his face was expressionless as always. Like there was no problem here.
