On a rainy night, Xia Nanqing picked up a beautiful young man soaked to the skin at the door of a convenience store. Like an abandoned puppy, he called her "sister" with wet eyes. She was kindhearted and took him in for a night, but she didn't expect to be stuck with him from then on. The boy was well-behaved and sensible, doing laundry and cooking, and his eyes always followed her. Until one day, she saw that familiar, yet cold and distant face on the cover of a financial magazine.
