Illustrator Ye Niannian originally intended to go to kindergarten to pick up her niece, but by a twist of fate brought back An'an, the only son of Huo Shiyue, the richest man in the city. This four-year-old child had been silent for eight months, yet was uniquely willing to speak to Ye Niannian. Ye Niannian was hired to live in the Huo residence and accidentally discovered that An'an had long been abused by Huo Shiyue's fiancee. She gathered evidence to protect An'an, and stood shoulder to shoulder with Huo Shiyue to resolve the Chen family's continuous revenge. Gradually growing closer through their day-to-day life, the two built a complete family. Years later, An'an, who had once closed off his inner self, became determined to research and develop AI, wanting to smooth out the barriers of "not being able to understand each other" between people, and rushing toward a life of his own in the pursuit of his passion.
