This is a beautiful story about childhood sweethearts. Elders Nan and Xu arranged a "baby kiss" as a joke, but little Nan Jin took it seriously. From then on: any boy who wants to kiss little Xu Nuo on the face is a pervert! Get rid of any boy who wants to give Xiao Xu a lollipop, so don't be kind! Get rid of any boy who says "you are so cute" to your little promise, it poisons your mind! Drive away. The most beautiful thing in the world, you give me the whole world. As warm as you, give me the whole world.
