Jake knows how this ends. Six months. Maybe less. So he writes a list of sixteen things he'll never get to do, closes the notebook, and decides that's enough dreaming for one lifetime. Then Heeseung walks in like a storm no one warned him about. Grumpy. Quiet. Impossible to read. The kind of person who shouldn't become important. But somewhere between long drives and quiet nights, Jake starts forgetting that the list was never meant to change. Because the cruelest part about time isn't how fast it runs out. It's how, sometimes, it gives you something beautiful just before it does.

No one speaks to him. No one dares to. Locked away in the psychiatric hospital, Heeseung is a walking nightmare-silent, calculating, and burdened with a past that remains a mystery. The doctors whisper about him in hushed voices, and the nurses refuse to meet his gaze. No one knows what truly happened, but they know one thing: he is dangerous. Then comes the new psychologist, Sim Jake. Young, ambitious, and unaware of the unspoken rules, he takes the case no one else will. He wants to understand the man everyone fears. He wants to know the truth. But some mysteries are better left unsolved. Did he succeed in breaking through the criminal's silence? Or did he, too, become just another story whispered behind closed doors?
