  A genius brain scientist with a “very special brain.” Shin Haru has nothing to fear in the world. He is ruthless to anyone whom he considers trash.

Despite his fearless and ruthless nature, the only reason he is considered charming is because of his special brain. He dreams of revenge on Detective Myeongsae, who brought down Haru when he was doing well, but somehow Myeongsae’s altruistic brain starts to grow on him.
