(Previously called Assassin Child)

Luhan is the epitome poster boy of silence. He had been that way ever since he was fourteen and had witnessed a crime scene of mass murder. Speaking only when necessary and when irritated, he keeps to himself as much as possible. Though five years had already passed since the incident, the Lion association: code name for the Assassin group that led the mass murder, is out for Luhan’s head. Reason? The commander is afraid Luhan will recall his memories that contain evidence against them.

Being the only surviving witness, Luhan had forced himself to forget the entire terrifying event, and all the trauma related. Partly to protect himself and partly to blur the face of the boy in the center of it all. Now innocent with a quiet and naive mind, Luhan isn't aware of anyone out to get him. And despite not realising it, he falls into a trap that leads him straight to the jaws of the lion.  

As Luhan remains far from his comfort zone of silence and introvertedness, the face of his strange white haired friend continually sending him into dazes of memories he no longer remembers, Luhan continues to climb the wall of blocked memories that protect him.

Sehun's own comfort zone is thrown from peace when he is threatened with his life by his father should he not get down to it and kill the witness. But as Sehun starts to see another side of Luhan, a side he didn't want to get involved in, he is pushed into a dilemma of life and death as he battles with himself between right and wrong, and a forbidden love that can cost him everything.
