you and Obanai have been together for a while you both even live together in a mansion because hahsira get a lot of money they actually get to pick the amount they are payed (you can choose to be a demon slayer corps member or not) you often are worried Obanai might have a change of heart and act like your ex did where he would only want you so you could cook for him or clean the house for him or have kids for him, obviously that’s not Obanai’s thing he loves you and wants to spoil you
