Sang Zhining pretended to have amnesia on a whim, but unexpectedly discovered that her boyfriend of many years had betrayed her. She decided to play it safe and let the drama continue. Xu Yanchu, Xu's eldest son, came into her life as her boyfriend, living under the same roof and seeing each other day and night. His gentleness and closeness were just right, so good that she almost forgot that this was just a transaction. When the lie was finally exposed, what she was waiting for was not the end, but a belated confession. Xu Yanchu had already been moved by Xu Yanchu when they first met three years ago, and now everything that comes close to her is a long-planned wait. This time, she chose to believe him.
