Song Yugui was once willing to sacrifice her life to protect the crown prince Zhao Heng, but she ended up being completely replaced by her substitute Li Sangyue. After resurrecting her life, facing the steel knife stabbing the prince, she coldly retreated and no longer acted as a "human shield" for anyone to manipulate. Faced with Li Sang Yue's moral kidnapping and her family's partiality and harsh criticism, she no longer tolerated it and took every step to tear apart the other party's hypocritical mask. When the carefully planned frame-up was exposed one by one, the prince was shocked to realize that Bai Yueguang, whom he regarded as a treasure, was just a scheming fake, and what he pushed away with his own hands was the sincerity that was truly worth cherishing.
