Li Yu is a pretty boy who is neither tall nor strong, with a venomous mouth and a fear of pain. He has been ignored by cats since he was a puppy. Ji Zhengyu is completely opposite to him. He is a typical child of other people, a sunflower under the sun. Li Yu said, "Bah! You can pretend to be Y. Are there any sunflowers like you who are always in trouble?" Ji Zhengyu glanced at him, and Li Yu obediently shut up. In short, this is a story about growth, about love, about a sinister prude and a poisonous little cutie.
