The ruined Seoul city center splits open as a black execution stage rises from the asphalt under a cracked star-filled sky.

The Star Stream expands the execution stage into a spectacle watched by survivors below and Constellations above.

Min-Su and Jae-Hyun are revealed chained on opposite sides of the stage.

A system pistol appears between Min-Su and Jae-Hyun, and the Scenario title is announced.

The Star Stream explains the sacrifice rule in plain terms as both friends process what it means.

The reward becomes personal when the system displays Seo-Yeon's district feed as Min-Su's registered family target.

The forced spectators and celestial viewers react to Seo-Yeon's feed and turn the sacrifice into entertainment.

Jae-Hyun pulls Min-Su back from the crowd's logic and makes him look at him as a person, not a rule.

The Architect of Betrayal interrupts with a private window only Min-Su can see.

The Architect frames the sacrifice as a practical choice for Seo-Yeon's survival.

The Architect donates 1,000,000 Coins, shaking the stage and overwhelming the broadcast.

The donation settles into a private order for Min-Su to pull the trigger.

Jae-Hyun tells Min-Su not to let the viewers define him, even if Jae-Hyun is the one who dies.

Min-Su moves toward the pistol as the stage interprets his hesitation as acceptance.

Min-Su grips the system pistol, and the Scenario locks him in as the chosen executor.

The Architect predicts Min-Su's private calculation before Min-Su can act on it.

Min-Su tests whether the Architect is reacting to his thoughts, while the timer continues to fall.

The Architect quotes Seo-Yeon's private childhood lullaby, a fact no sponsor should know.

Seo-Yeon's feed and Min-Su's memory collide, confirming the lullaby was private.

The Architect's avatar glitches and exposes an impossible older face beneath the mask.

The Architect regains control of the window and orders Min-Su to finish the sacrifice before the timer ends.

Min-Su walks to Jae-Hyun with the pistol, torn between the visible rules and the impossible sponsor clues.

Min-Su raises the pistol to Jae-Hyun's forehead while privately questioning the Architect's impossible knowledge.

Min-Su asks the Architect who he really is while the execution timer reaches the edge of penalty.
