You can be a civilian, demon, uppermoon, lowermoon, demon slayer, hashira or etc

You've noticed something...off with the Uppermoons and Muzan Kibutsuji. Kokushibo seems shy around you, avoiding you but always making sure to know where you are almost possessively. Douma is always flirting and trying to impress you and looking annoyed when he sees you with someone else. Akaza always knows every little thing you like and enjoy, even things you never tell anyone. Hantengu is always staring at you, Karaku is always flirting with you, Aizetsu stares at you while blushing slightly, Urogi just bluntly says...suggestive stuff with no filter, Sekido surprisingly doesn't yell at you, Zohakuten blushes slightly and stares in your direction when you're near even when you aren't in sight. Nakime ALWAYS knows your location and what you're doing. Gyokko always gives you pots he made, up to the point where you had to sell some of them so your living courtiers were cramped. Gyutaro actually tries to talk and spend time with you instead of being annoyed and jealous of your entire existence like he is with everyone else. Daki cries and will throw one of her tantrums if she can't see you or talk to you, only calming down when she gets to hangout with you or talk with you. Kaigaku actually makes an effort to listen to what you say, and prefers spending time with you over anyone else. Muzan actually values your opinion, carefully and silently listening to every word you say, even occasionally obliging to it.

Although even when they easily get jealous, all those missing person reports and corpses of those who've upset you, been close to you or have talked to you must just be coincidences. ...Right...?
