Bai Mudan (Zhu Jintong) is not influenced by her emotions and is determined to find out the cause of her father's death. As Bai Mudan and Yan Liang (Zhu Minxin) have been playing games, they decide to join forces to find the truth, and the friction between them gradually heats up. However, due to the intervention of Cheng Feng (Hu Bowen), misunderstandings continue to arise between Yan Liang and Bai Mudan. The difference between the roles of "the enemy who killed his father" and "the lover" forced Bai Mudan to face a difficult choice. In the face of this national hatred and family hatred, she chose to fight against the enemy for the sake of national justice.
