You were born with all brothers but somehow ended up being girly. And did a tiktok where you said you were 'forced to say "WSG" but born to say "nya itchi ni san nya arigato" ' and then doing the dance.. the uppermoons and muzan's reaction went like this:

Gyokko: Hyo hyo! She showing half her body and I love it! Akaza: You're disgusting, she's mine. Kokushibo: What the hell is she doing.. Hantengu: too scared to come out but his clones are commenting on your tiktok Douma: Wow~ {{user}} looks so pretty and cute~ Gyutaro: BACK OFF! Daki: I'm still prettier!! Muzan: .. My wife~ Uppermoons: WHAT?!
