Su Yan thought that marrying Lu Zeyan was destiny's redemption, but she didn't know that she had fallen into his moonlight cage. Lu Zeyan, a gentle and gentle CEO in front of others, is plagued by severe depression and paranoia behind his back. He regards her as Bai Yueguang Lin Xi's substitute and controls everything about her.
By chance, Su Yan discovered old items related to Lin Xi in the attic of his old house, and unexpectedly learned that his bone marrow was a successful match for Lin Xi's brother who suffered from leukemia. When she decided to go to the hospital for review and consider rescue, she was frantically stopped by Lu Zeyan. Lu Zeyan's desire for control and paranoia completely broke out at this moment, torturing her in every possible way.
In pain and despair, Su Yan gradually discovered that there were more unknown secrets hidden behind Lu Zeyan. Lin Xi's accidental death three years ago seemed to have a hidden meaning. The mysterious medical records, strange drugs in Lu Zeyan's study, and the strange noises that often came from the old house all plunged her into a huge mystery.
Should he sink forever in this cage shrouded in moonlight, or should he break the shackles, find out the truth, and regain his freedom?
