When the eighteen-year-old An Xin stood in front of the carved iron door of the Shen family villa, she thought she was grabbing a piece of driftwood to save her life, but little did she know that it was a gilded cage tailor-made for her by fate. The dual identities of an orphaned girl with a poor family and a "Yao Yin" with a special bloodline made her a necessity in Shen Yanci's life - the Shen parents said that only her aura could suppress Shen Yanci's "stubborn illness", but no one told her that the price of "extending her life" was the loss of freedom.
Shen Yanci was the controller of this cage. He built a high wall with indifference, stipulating her daily routine, social interactions, and even what color skirt to wear. When the thin calluses of his fingertips passed through the top of her hair, there was a tremor that even he was unaware of. An Xin hid the flames of escape in her meek eyes, and accumulated strength in the "Qi Crossing" ceremony day after day, until the conversation she accidentally bumped into late at night completely shattered her perception - Shen Yanci's cough was a disguise, her paleness was makeup, and the Shen family's seal was clearly printed on the list of her family's destruction.
When her hatred broke out, she realized that she had become his weakness, just like he had become a shackle that she could not break free from. When the diary fragments in the secret room reveal more truth, and when Shen Yanci falls covered in blood in the rain to protect her, An Xin finally understands: the web of fate has been woven as early as that sudden glance in childhood. He trapped her with paranoia, but she locked her heart with affection. The so-called cage is never the high wall of Shen's house, but the sinking that cannot be hidden in the eyes of the two of them every time they look at each other.
