Yoon-jin leans forward. For the first time, her voice cracks. “Your sister’s killer is still out there. I framed you to keep you alive. Prison was the only place he couldn’t reach.” So-ri places both palms flat on the table. No cuffs. No guards. SO-RI: “Then let’s go catch a ghost.” They don’t hug. They don’t cry. They just look at each other—and the silence between them becomes louder than any scream.

Last spoken by a fishing village that was drowned in 1987 to build a dam. He didn’t hear this word. He excavated it.” The camera pushes in slowly. We see Yoon-jin’s hand tremble—just once. YOON-JIN: “Why did you burn the evidence warehouse?” So-ri smiles. It doesn't reach her eyes. “Because you asked me to.”
