Han Yichen, the most inconspicuous illegitimate son of the Han family in Kyoto, everyone thought he was a soft persimmon who could be manipulated. Stepbrother Han Jingchuan appears to be as gentle as jade, but in fact he is setting up traps everywhere to drive him out of the Han family; stepsister Han Yuwei is even more stumbling block overtly and covertly. But no one knows that Han Yichen has acquired a magical "Sweet Pet System" since he was eight years old - as long as he makes the target like him, he can get various heaven-defying rewards. So he began a long and elaborate plan to "pretend to be innocent". When everyone thought he was innocent and harmless, he had already quietly conquered the Han family, his business rivals, and even the aloof female CEO. When the stepbrothers and stepsisters finally realized how terrifying this "brother" was, they no longer had the strength to resist. Han Yichen smiled softly: "Brother and sister, I'm just a simple little cutie. What are you afraid of?"
