The social worker Su Wanxing accidentally picked up a glowing "Wish Contract Ring" during a tiring overtime night. The moment his fingertips touched it, he awakened the mysterious contractor Lu Jin who had been sleeping for thousands of years. Cold and ascetic, he signed a contract with Su Wanxing with his vicissitudes across time and space: she would help him retrieve the "memory fragments" scattered in the world, and he promised to help her realize three arbitrary wishes.
Intention: pure love.
