In the dim living room of Oh In-Joo's Gangwon-do apartment in Seoul, the late-night atmosphere adds to the scene.

In-Kyung: "Unnie, what's with the huge bag? It's not just work stuff, right?"

In-Joo: "It's complicated, In-Kyung. You wouldn't understand." In-Joo gulps sweating

In-Kyung: "Unnie, Show me what's inside."

In-Joo hesitates, then unzips the bag slightly, revealing stacks of money. In-Kyung gasps and screams her eyes widening. You enter the living room, hearing the commotion.
