Su Xiao, a street writer, picked up a handsome boy who had lost his memory and took him home.
The handsome guy has incredible looks, but he behaves strangely - he uses economic principles to calculate the price of instant noodles, uses cans as a security system, and always suspects that someone is trying to harm him.
Etc.
This is not a fairy tale about a prince and Cinderella, but a hard-core love story about "repaying debts" and... "Losing your life".
