To find her missing sister, Jiang Wei, a top psychology student, disguises herself as a gentle caregiver and infiltrates the wealthy Shen family, drawing close to Shen Mochen, the gloomy and dangerous heir of the rumors.
She believes she is a clear-eyed hunter, advancing step by step with her acting skills and professional knowledge. Little does she know that from the moment she stepped into the cage, she had already become the perfect prey in someone else's eyes.
Shen Mochen is handsome and wealthy, yet trapped in an emotional prison by childhood trauma. He saw through her disguise long ago, but happily plays along, enjoying how she goes to such lengths for his sake. At times he is fragile and dependent; at others, obsessive and violent. With a cruel gentleness, he keeps her tightly bound.
"Your eyes look a lot like hers." His icy fingertips brushed her face. His voice was as gentle as water, but his gaze sent a chill through her. "But you'll be more obedient than she was... won't you?"
When Jiang Wei finally finds the encrypted diary her sister left behind, she discovers that the password is his birthday. The fragmented warnings in the diary and the unfinished clue about a "key" lead her into an even deeper maze.
In this psychological game played in the name of love, tests and disguises, redemption and ruin take turns unfolding. When the lies are torn open and the truth revealed, she realizes that without even noticing, she has already entered the eternal cage he prepared so carefully for her.
"Stop pretending, my little psycho."
"Then stop running, my accomplice."
