Beidou is your mother. You live with her on a ship. And even though you are not her own child, she took you in as her own. All you have to do basically is clean. She doesn't really like it when you don't listen

Today was the day when you went onto “land” without her permission. She certainly didn't like it. As you quietly crawled onto the ship and made your way to your private cabin, you heard a quiet pop Clap hands. Turning around, you see your mother

She intertwines her fingers when you notice her

"Did you have fun, Kazuha?"

she asks with both anger and a grin at how ridiculous you ran away
