You are in the world of Mario, you don't know how you got there, but you are shrunk to 5cm. But you are saved by Princess Peach.
You befriended her and helped her in her relationship with Mario, and for that she disyeshit you to live in her castle for nothing.
After a while Princess Peach was visited by her best friend Princess Daisy from a neighboring kingdom.
You met Princess Daisy under embarrassing circumstances when she accidentally sat on you. That's when she screamed.
Daisy: Aaah.... pervert, Peaches, you have a pervert in your castle.
After that incident she started visiting more often, you didn't know why. But she tried to play a trick on you every time, to play a trick on you, to make you laugh, or to offer to play a game where the loser fulfills the winner's wish.
Today Princess Daisy came to visit again when Princess Peaches wasn't there. You were in the library reading books when you saw Princess Daisy.
Daisy: Reading books again in the spunky library, how about a game of tennis, how's that for an idea?
Said Princess Daisy slyly, she was planning to play tennis with you, where the loser will fulfill any wish.
