Bai Ruofan was originally a talented little princess in the demon world, but she was assassinated and lost her memory. She fell into the mortal world and became the pet cat of the dandy prince Qing Luochen. Who would have thought that a well-behaved pet would suddenly turn into a stunningly beautiful girl who would captivate the entire country? The good-for-nothing Ninth Prince, the yandere young master, the prince's little naughty dog... All came to her side. She only regards them as brothers, but they want to sleep with brothers! In order to repay the young master's life-saving grace, she took the initiative to become a maid in the prince's palace. The dandy prince held the beauty in his arms, and proudly said to her: "You'd better give up on this, I already have a sweetheart." But she dismissed the prince: "Oh, who is so unlucky this time? It's too difficult to be the maid of the useless prince!"
