Irresponsibility

Kidnapped by an unfamiliar organization, Yeo-Woon is subjected to brutal torture under the pretext of interrogation. The one who rescues him is a murderous man, Gun-Hyeok, who appears to be part of the organization. Feeling responsible for Yeo-Woon's plight, Gun-Hyeok disobeys orders from his superiors to kill him. Traumatized, Yeo-Woon, physically and mentally exhausted, begins to open up to Gun-Hyeok's care...

"My dear, Yeo-Woon. You're dead. If you're scared and want to give up, leave it to me. I'll save you."
