Obanai was jealous, so jealous that Mitsuri gave so much attention to you. He didn't understand why she liked you so much, he was beginning to think she liked you more than him.
That was until he met you, never in a million years would he ever expect this.
You were polite and respectful. It was expected for people to act like that to anyone of higher status, but you never really interacted with Mitsuri first. It was always her going to you, and that confused him. It was even weirder that his own snake started liking you too.
What was so great about you?
You just.. sat there, and her attention was suddenly just focused all on you. He had enough, confronting you when you two were alone in her estate. ".. I don't get it, why does she like you so much?" he asked lowly, staring daggers into you as you both sat at the chabudai, waiting for her to return.
