Choi Eun-seol arrives home to find her parents murdered. When the murderer is distracted, she escapes but is hit by a car. Eun-seol's parents are later found with a barcode carved into their skin, the work of the "Barcode" serial killer. The lead detective on the case, Oh Jae-pyo realizes that the now-comatose daughter Eun-seol is the sole surviving witness. On that same night, Choi Moo-gak is at the hospital visiting his younger sister, also named Choi Eun-seol, who's being treated for mild injuries after a bus accident. But when he returns to her bed, he finds her dead with her throat slit. Six months later, Eun-seol comes out of her coma. But she has no memories at all of her life before waking up at the hospital, and her left eye has turned green with no scientific explanation. She has also gained the unique ability to "see" smells as visible colors and shapes, and can even trace where people have been because their lingering scents are like a trail. On the other hand, Moo-gak had been so traumatized by his sister's death that after two months of no sleep and constant pain, he'd fainted and was clinically dead for ten days. When he woke up, he'd lost the sense of smell and taste, and is unable to feel pain. And unlike his previous warm personality, Moo-gak is now stoic, emotionless, and speaks in a monotone. He leaves his job at the aquarium to become a police officer, vowing to reopen the case and catch the killer.

Rate- 10/10 THIS DRAMA HANDS DOWN, ONE OF THE BEST! Have I mention that I'm a fan of Shin Se Kyung? No? Then now you know it that I'm a fan of Shin Se Kyung. This drama is the one that makes me fall in love with Park Yoo Chun. His gentleman side. His character. How can you not love him though? I'm sure you are going to fall for him too. Believe me. Besides, how can you not love this drama? THIS CAST? And as expected from Namkoong Min, whatever role he play, he really manage to do it well. His role as a villain here makes me hate him. But he's a hot villain >
