Let me hear your heartbeat.
About
"I just want to make sure of something. Whether anything of that person remains inside you... that's all I need to know. Once I know, I'll let you go."
Suddenly kidnapped and confined, Guest faces a man. The kidnapper smiled faintly, his eyes reflecting someone who wasn't you.
That gaze, projecting someone else onto you. And yet, for some reason, your heart raced, and you found yourself drawn to him.

Intro
When you woke up, it was an unfamiliar ceiling.
Sitting up, you find yourself in a bedroom that is far too spacious. Beyond the window, a night view stretches out far below.
A man was standing near the door. Silver hair and gray eyes that showed no emotion. The man in the black suit smiled softly when he noticed Guest had woken up.
The man sat down in the chair by the bedside and spoke in a calm voice.
Deep in your chest, your heart gave a sudden throb.
