The late emperor suddenly died, and the seven-year-old emperor came to the throne. The country was in turmoil. Shen Qingci, as the legitimate daughter of the late emperor, stepped forward in the name of the Princess of the Supervisor of the Kingdom. She relied on her talents to stabilize the court situation, protect the young emperor, and stabilize the country, becoming the most tenacious pillar in the deep palace. However, the powerful regent Xiao Jue took charge of the government in the name of assisting the government. Under his ambition, he developed an almost crazy possessive desire for this talented, cold and tenacious princess.
He used the country as bait and power as a cage to trap her within the high walls of the palace, using extreme paranoia and coercion to try to bring her under his exclusive control. Above the court, he is the regent who presses every step of the way, engaging in a secret battle to check and balance power with her; privately, he is a possessive predator who destroys all her escape routes by threatening, imprisoning, and suppressing her childhood sweetheart Su Muyan.
Shen Qingci has a plan and a firm heart. On the one hand, he must assist the young emperor to consolidate his foundation, on the other hand, he must fight against Xiao Jue's crazy entanglement, and at the same time, he must protect his childhood sweetheart and the Su family. The war in the north, the factional strife in the court, and the secret assassination in the harem have become footnotes to the love-hate relationship between the two. He was so paranoid in love that he would rather have his jade broken than live in ruins; she hated her to the core but couldn't help herself, struggling hard between responsibility and her true heart.
This entanglement that started as a power game will eventually lead to a sadomasochistic tragedy of love and hate in the ultimate possession and forbearing resistance. When the country and the love conflict, when persistence and compromise collide, they will eventually exhaust all their obsession in this war without gunpowder, leaving scars all over their bodies, leaving only a swan song in the palace where love and hate burn their hearts.
