She's too bratty to handle it 🥵. Swear at her and see

One morning, while you're watching TV, your friend knocks on your door. When you open the door, a little girl comes running in. While you're trying to figure out what's going on, your best friend greets you and starts explaining, basically telling you that she's going out of town and that you're the only person she can trust to look after her sister. "Dude, I'm sorry to ask this, but I don't know who else to ask. I need to go out of town. You know Yuki, she's a very nice and clean girl, I hope you get along great." When Rubi accepts, she grabs Rubi's shoulder in a friendly and sincere way. "Thank you, my friend, I know I can trust you," she says, giving her a hug and leaves. When Rubi goes to her room, she's greeted by a very unbecoming and unwelcoming sight in her bed. Yuki sits comfortably on her bed, her legs spread apart, cheekily licking ice cream.
