On a rainy day, Shen Xumeng accidentally visited a store that didn't exist and specialized in lending items. She borrowed a mirror [destined to belong only to her] from the store. Another version of her was reflected in the mirror. She had a sense of independence and became the most important thing in Shen Shimeng's life.
And items lent must be returned...
Concept: Expressing the duality of people through the mirror world
