Song Ran was reborn and returned to the Republic of China for three years. When escaping from the mountain village, he ran into the arms of the cold-faced marshal Gu Yuanting. In order to regain her life and engagement that had been replaced by a fake daughter, she entered the school, attended banquets, and followed the conspiracy step by step. Gu Yuanting fired three times to scare the villains and guarded her silently. The two work together to expose the frame-up and go through wars, but they also deal with the whirlpool of real and fake daughters and family feuds.
