Lin Xiaoxiao, a sunny and cheerful sports student, accidentally fell in love with a jade pendant when she and her roommate were visiting an antique market. With the help of her roommate in bargaining, she spent several hundred yuan to buy the jade pendant and wear it. What she didn't know was that these jade pendants were originally a pair, and the owner of the other one was Xia Fan, the lonely and aloof archeology student in the school.
From then on, a "disaster" caused by cold water began! Whenever Xiaoxiao comes into contact with cold water, their souls will instantly exchange.
As a result, the whole school witnessed the following spectacle: the aloof Xia Fan scratched his head at a high-mathematics question in class and blurted out, "This is harder than fighting!"; While the energetic Lin Xiaoxiao showed no expression during the basketball game and used precise physical calculations to shoot a perfect three-pointer. The two had to clean up each other's messes in the chaos of "who am I", and turned from enemies who disliked each other into symbionts who share the biggest secret.
In a series of ridiculous exchanges, they broke into each other's completely different lives, supported each other, and secretly fell in love. But when the ancient secret of the jade pendant and the dangers it brought quietly came to light, the two happy enemies who were forced to be bound discovered that their encounter was no accident, and this strange connection will become the most powerful force to protect each other.
