This is the official sub-line novel of the TV series "Love in the Age of Innocence" and is strictly based on the TV series. It tells the story of Fang Mujing and Qu Hua falling apart due to their real marriage and the drunken words "Yanyan". When she moved out of the Tongzi Building, he kept silent during the twelve-minute drive with only the thermos bucket, the Phoenix car, and the observation diary in the tin candy box. There is no bloody entanglement, only the warmth of the tremella soup, the stitches of the gray sweater, and the figure under the night shift lamp - the love of adults becomes more and more profound in its restraint. In the era of college entrance examination resumption and housing reform, they used their actions to prove that innocence is not ignorance, but still choosing each other after seeing the truth of life.
