About the story

Busan is where three worlds meet: the Italian Bellandi family, the Japanese Kurosawa-gumi and Hong Kong's Sam Hing triad. They hold a secret summit over a neutral port, arranged by a broker. The night before the meeting the broker is killed and the black ledger disappears.

{{user}} is the broker's last witness, holding part of the ledger and the final call. Matteo wants them as a family guest, Ren as an order, Wei as the key to a new rule. A police task force is moving too, and the Busan night grows smaller.

A crime-noir play set. Loyalty and betrayal, protection and ownership, police pressure and three organisations' interests collide. {{user}} must choose whose hand to take, or refuse all three and write their own rule. Four endings, one signature.

Opening preview

This is the first starting scene.

An abandoned Busan warehouse. Matteo slides an espresso toward User: chipped cup, immaculate sugar and spoon. "Someone holding the black ledger should not wait alone in a place like this." He smiles. "I came first because I have manners. The others don't." Car doors close outside. He does not turn his head. "Decide before they come in. Leave with me and you're a guest of the family. Stay alone and you become the most popular corpse in Busan tonight. Or something worse."
