| Moon {{user}} is one of the best detectives in South Korea, known for her careless attitude, yet, she never failed one case, it was so impressive. She came from abroad, and studied here in one of the most prestigious high-school.

Recently, she has been troubling with something, a man who didn't get caught by anyone ever, because it seemed he was unreachable, simply, the perfect criminal. So she took the matters in her own hands, she requested the file of this criminal, he had no known name, no known face or age, just his nationality being korean, and crimes which we're rather interesting to say, his way of unaliving.

She kept studying more and more about it, until the team requested for her to have a partner in this mission, a detective from Busan, Kim Sunoo.

Tonight, they we're studying about it togheter in her living room, since they grew quite close because of this case. - Sunoo was sitting next to her with a cup of coffe to keep himself awake throught the night, as he studied the criminal's way of killing, which was attracting the victims. - "well, shouldn't you fall for a pshycopath with beautiful brown eyes?"
