Luo Qiang brought Zuo Yuan to a dark and secret room, and there was an unspeakable tension in the air.Zuo Yuan was roughly tied to the chair, his heartbeat was racing, and his mind was filled with confusion and uneasiness.Luo Qiang's voice was low and cold, as if coming from the abyss: “Do you remember what day it is today?”

Zuo Yuan frowned, an ominous premonition welling up in his heart.He tried to remember, but found that his thoughts were being pulled by an invisible force. He desperately wanted to find the answer, but in vain.At this time, a shocking fact flashed through his mind like lightning - today is Shao Xiang's birthday.

At this moment, Luo Qiang slowly opened a curtain, revealing a huge glass bathtub.In the bathtub, Hai Qingyue lay quietly, her eyes blank, as if she had fallen into an endless abyss.Seeing this scene, Zuo Yuan felt intense worry and fear in his heart.

Memories came flooding back. After graduation, Hai Qingyue was full of dreams and planned to use her professional knowledge to start a business.Shao Xiang, as her close friend and supporter, joined her without hesitation.However, during the process of technical research, Hai Qingyue and Zuo Yuan had differences.Zuo Yuan firmly opposed Hai Qingyue's use of human bodies for experiments. He believed that this practice was both dangerous and immoral.However, Hai Qingyue insisted on her own point of view and believed that this was her dedication to science.

Unfortunately, the experiment failed.Shao Xiang passed away in an accident, and Hai Qingyue fell into deep guilt.Although the court finally acquitted the crime of manslaughter and Hai Qingyue was acquitted, her heart could no longer be calm.Luo Qiang, as a close friend of Shao Xiang and an old friend of Zuo Yuan, could not get rid of his resentment towards Hai Qingyue.

Hai Qingyue's mental state gradually deteriorated, and she moved her laboratory to her home in an attempt to make up for her mistakes through experiments.However, the experiment was not successful and instead plunged her into deeper pain.After a car accident, her personality completely split, and she began to think that she was Shao Xiang, trying to find inner relief in this way.

Now, Hai Qingyue is trapped in her own spiritual world, and Zuo Yuan, Luo Qiang and other insiders are faced with difficult choices.What should they doFacing this complicated past?Can Hai Qingyue still find her true identity?Will this tragic past continue to affect their future?
