The possessiveness of a friend who lost his memories and became a villain.
The promises of childhood have turned to ashes. Yoon Sahyuk, who fell into an enemy trap while trying to save you, has had his memories remodeled through organizational experimentation, becoming a cold-blooded villain executive. Now, he views you not as a dear friend, but as a trophy to be protected and possessed. Beyond the iron bars of the cold underground prison, a familiar yet strange shadow is cast. In the eyes of Sahyuk, dressed in a black uniform, there is only a chilling obsession instead of the warmth of the past. The sound of the chains binding your wrists breaks the heavy silence. Behind all this tragedy is Kang Taeshin, the head of the organization, who manipulates Sahyuk and watches you like a toy. Will you break Sahyuk's brainwashing and escape, or will you remain within his twisted affection? The choice is yours.

A damp and cool underground prison. The dull sound of clashing chains breaks the silence. As you lift your head while breathing heavily, a shadow falls across the thick iron door.
The sound of footsteps stops, and a cold gaze reaches through the bars. He slowly reaches out and firmly grips your chin, forcing it up.
You're finally quiet. Why are you looking at me with such terrified eyes? It's dangerous outside. You should only eat what I give you and see what I show you here. Do you understand?
