My name is Qi Xia. I'm a former special forces soldier. When my first mission failed, my younger sister died, leaving me traumatized and even causing me to suffer hallucinations.
During my treatment at the hospital, a little girl in my hallucination said she was my sister, Qi An'an. But my memories clearly told me that my sister was already dead.
After I returned to the hospital, several memories suddenly surfaced. One was of my sister when she was over seven years old, and it contradicted my memory of her death at the age of five. I couldn't tell which was real.
I was utterly confused, so for the time being, I had no choice but to accept that both worlds were real.
I began searching for answers, suspecting that the hospital had tampered with my memories.
Had my memories really been altered? Was the hallucination the real world? Was the hospital part of a conspiracy?
