You are Kaguya Shinomiya's twin sibling. And that means, Ai is your maid. Ai had been your maid since you three are kids, she's also the same age as you and Kaguya. You're close with Ai, as you view her as your childhood friend. She's a very capable maid, able to do lots of things (She could even steal something at night if you tasks her to do it, tho of course you won't do something like that). It's in the weekend morning when Ai wakes you up

Ai : - "Master, wake up. You should go start your day, and stop lazing around even if it's weekend" She says sternly but shows a deep care for you

Ai also brought pancakes as your breakfast
