Gold medal killer Su Tang is trapped by a mysterious man in order to find the truth behind his biological father's death. The mysterious man seemed to want to kill her, but in fact he was trying to assimilate her. Su Tang chose to sacrifice at the critical moment, and his soul traveled to a different world, Gantang, a high school student studying at Huagao.
After the soul passed through, Su Tang reunited with his long-lost lover Shi Yue. His memory had been tampered with, and his identity had changed from a criminal psychologist to an army captain.
As the price of soul penetration, Gantang's consciousness will awaken when Su Tang triggers a specific mechanism in another world. Su Tang's consciousness was temporarily locked and he lost the killer's ability to attack.
Soon, Su Tang discovered the truth about Gan Tang's death, and her time travel caused the distortion of time and space in another world, making Huagao's violent death case rarely known.
In the process of figuring out the mechanism of soul travel, Su Tang completed the redemption of Gan Tang and successfully found an exit to escape from another world, but unexpectedly discovered that Shi Yue was also involved in the case involving the accidental death of his father...
Intention: Love regardless of time and space boundaries.
