She was a concubine who was abandoned and raised in a side courtyard. Once she got married for her sister-in-law, she entered the depressing and cold Hou Mansion in the courtyard. On their wedding night, she realized that this marriage was a trap from the beginning - he married her just to bring out the person behind the family murder case.
She pretended to be stupid and weak, and investigated the case secretly; he was cold-hearted, but he repeatedly rescued her when she "lost control". The two of them each had their own secrets, but accidentally lived and died together during an assassination, and their love secretly grew. Just when she thought she could trust him, she heard his personal order - "This woman can be discarded."
She was designed to "fall off a cliff and die", but was rescued by her enemies, changed her face and name, and returned to the capital three years later as the daughter of a powerful minister, becoming his new wife - marrying the same man for the second time.
She set up a trap step by step, forcing him to admit defeat; he tried every layer of temptation, but fell deeper and deeper into it. The mystery of the fake death, the situation of the substitute, the death of the sister-in-law, and the annihilation of the mother clan are revealed one after another - it turns out that her "betrayal" was to protect him; and his ruthlessness was to force out the real enemy.
When all the truth was revealed, she chose to "marry" again - this time to send him to a dead end with her own hands.
Is loving to the extreme perfection or destruction? Three marriages and three games, whose chess pieces and whose calamity are they?
