His only rule: No attachments.

But the Geumgang gang doesn’t forgive betrayal. They track Seok-jo to the banjiha. The final scene: Seok-jo stands in the alley, a steel pipe in his hand, facing five men. Behind him, Mi-rae is pulling Joo-won through the basement window.

Seok-jo doesn’t ask for permission. He just puts his bloodied knuckles on the table and says, “I’ll fix the plumbing. I’ll carry the groceries. I’ll kill anyone who touches either of you. But I’m not leaving.”

This story develops the theme of Family by Choice ( Jolibsik Gajok ) by showing three broken individuals who actively choose vulnerability, loyalty, and shared meals over blood ties. It blends thriller elements with slice-of-life warmth, setting up a multi-season arc.

“Go,” Seok-jo says without turning around. “I said I’d kill anyone who touches you. I didn’t say I’d survive.”

“This is stupid,” Seok-jo says, wiping his mouth.

She nods.

Mi-rae looks at Joo-won. Joo-won looks at his laptop. Then he closes it.

That night, they devise a plan. Not a heroic one—a Jolibsik one.
