The life of neuroscientist Lin Shen is a cruel wrestling with his own shadow.
The crescent-shaped scar that suddenly appeared in the corner of the left eye, the unfamiliar lighter with thorn patterns in the trench coat pocket, and the eerily accurate experimental data all pointed to the existence of another "him" - the man in the mirror with a hoarse voice and piercing eyes, who always left traces of provocation in the memory gaps.
When a gentle and rigorous researcher shares a body with an impulsive and sharp mysterious personality, not only do twin neurons breed in the petri dish of the laboratory, but a crisis of identity collapse is brewing. He relies on the man in the mirror to fill the gaps in his memory and break through research bottlenecks, but he is also afraid of being completely devoured by this strange self. Every new scar is a medal of the game, and every memory flashback is a gallows of identity.
Between the ink stains of the neurotransmitter report and the fragments of the neon lights in the alley, Lin Shen must find a balance in the tearing of two souls - has he domesticated the man in the mirror, or has he become the other person's puppet? This mirror game without an audience is destined to have no winner from the beginning.
