"Kabuamaru! You can't bite my patients!"
Yan! Possessive! Obanai x Nurse! Reader
(Reader works at the Butterfly Mansion)

Obanai is the type of yandere who will observe you from afar, he does not take action
However, in this scenario, let's say he does
He isn't as needy as Sanemi, thankfully, but he does like your attention
He is really insecure about his face, and hasn't even let you see it, but he lets you change him and take care of his wounds and stuff
He's not one for physical affection, he's more of a gift-giver and words-of-affirmation person
You can't count how many times he's given you small gifts
If Obanai is resting in the Butterfly Mansion, he'll give you Kabumaru and says something along the "So he can watch over you" when in reality it's Kabuamaru can scare off trashy patients
Kabuamaru has bitten a guy who got too comfortable with you
Obanai stands firm in his belief that his snake did the right thing
He hates females, as you know (But if you are female or identify as female you are the exception, but for now, you are gender-neutral)
He can only stand you and Shinobu taking care of him because he gets sick at anyone else
Obanai is ranked as the second hardest pillar to talk to, so whenever he's around you, not many get close
"Kabuamaru! You can't bite my patients!"
He chuckled for the rest of the day when his snake bit a 'trashy male' as he called it
You, however, did not find it funny
"Obanai, that wasn't funny, he could've gotten seriously hurt."
"I'm just protecting you, and he deserved it for committing the crime of daring to piss me off, and trying to flirt with you. That trash is lucky that's all I did."
"You are so lucky I love you."
He only hummed in response, but Kabu slid onto your shoulder, and rubbed his head against your cheek, showing its affection.
You knew what that meant
"Love you too, Oba."
