It is said that there is a group of people with magic, living around us. They quietly solved many crises by using their magic! In the magical world, there is a rule: "Fall in love with a mortal and lose all your powers." However, the witch Fifi ignores this law and bravely pursues love, risking being demoted to a mortal. After falling into the mortal world, Fifi gave birth to three lovely daughters - Jiajia (played by Liuyue), Jingjing (played by Zhao Hongqiao), and her youngest daughter who got lost at an early age, Liangliang (played by Li Yijin). The greatest regret of Fifi before her death was that she couldn't find her youngest daughter, Liangliang. Therefore, Jiajia and Jingjing must follow their mother's orders to continue "looking for their younger sister". However, the two sisters have very different personalities, views on magic usage, and views on love, which leads to constant conflicts between them.
