"they told me green is not a creative color."

Joonmyun values himself as an adept addition to his branch of the FBI, a man capable of great things but humble enough to accept any compliment with a level head. A keen attention to detail and strong sense of justice brought him into the office, and has kept him here for three years. Although young when compared to many of the other agents, age becomes nothing but a number as soon as a sharp mind comes into the picture on the vast, dangerous playing field of criminal America. He's one of the best agents they have, and he's very aware of the fact. So why would he be surprised when he's assigned to a case investigating a serial killer?

Paired up with two agents; the reserved and logical Im Yoona, and Kim Jongin, a brutish youth known for his techniques used on the culprits, Joonmyun finds himself responsible for solving the case of the Green Eye killer.

Having to solve a crime, locate the culprit, and put them behind bars before they strike again is a heavy weight to have on one's shoulders, being juggled with the fact that "Oh, you're probably going to be targeted by the killer".

Joonmyun knows this. Is he scared? Definitely. But that doesn't mean he isn't going to put his all into this case and get to the bottom of it.

It's his duty to keep the citizens of America safe. When they're endangered, that means it's time for Kim Joonmyun to step in and take names.
