As a child, Shin Woo-jin was kidnapped and locked away in a warehouse, forced to live as a slave. But against all odds, he was rescued and finally stepped into the outside world. Though free, Woo-jin wasn't like other children. He had an extraordinary gift: the ability to read people. By observing the smallest facial expressions and unconscious gestures, he could see through their thoughts, emotions, and intentions with near-perfect accuracy. Like a profiler, like a modern-day Sherlock, Woo-jin learned to navigate the world, one observation at a time. But for someone who sees too much, living an ordinary life is the hardest thing of all. All he ever wanted was a peaceful, simple life. But the world had other plans. "As I thought... living a normal life is far too difficult."
