Before dawn in the Ardent library. Rain taps the tall windows. A single candle burns low over scattered ledger pages, Dahee's stolen notes, and Caelum's loop records. Both are exhausted but focused, keeping their voices low.

Dahee and Caelum compare the original webtoon structure against Caelum's records. The library feels like a war room made from stolen time.

The two find a repeating visual symbol in the records: roses as death flags. The mood shifts from investigation to disgust as Dahee realizes the art direction itself was part of the trap.

Dahee and Caelum leave the library and enter a corridor lined with portraits of former duchesses. The portraits are unnamed in the art, their faces solemn, their frames carved with roses and hidden inscriptions.

Maren nearly discovers Dahee and Caelum in the portrait corridor. Caelum masks the investigation as an order, forcing Dahee back into the role of maid while keeping her close.

The forbidden archive is guarded by Captain Rook and ducal guards. Caelum uses rank to pass, but the human discomfort in Rook's face reminds Dahee that everyone in the castle is trapped by duty in some way.

Inside the forbidden archive, Dahee and Caelum search through ledgers. The room is old, airless, and full of records that make the loop feel bureaucratic rather than magical.

Dahee finds ledger margins that line up with chapter numbers from the webtoon. Caelum watches as her outside knowledge becomes a practical map.

A tucked-in illustration of Seraphine appears inside the archive documents, treated less like a person and more like a promised solution. Caelum's old annotations undercut the promise.

The ledgers point to the chapel altar. Dahee and Caelum understand that the oldest rule is hidden where every political marriage in the duchy is blessed.

Dahee and Caelum enter the chapel. Sunlight through stained glass paints the stone floor red and blue. The altar looks holy from above, but the underside is built like a locked mechanism.

The oldest rule is carved beneath the chapel altar. It is not written in a ledger or a romantic poem, but in the foundation stone itself.

Caelum explains the rule in plain terms. The carved condition clarifies why every rescue failed: if the chosen woman refuses to die willingly, the plot forces a death through Caelum instead.

Dahee and Caelum step into the courtyard. Afternoon light hits the white stones. One old bloodstain remains faintly visible where Livia died in previous loops, and Caelum instinctively avoids it.

Back in the archive, the investigation becomes intimate. They work shoulder to shoulder over a torn page, both pretending the closeness is only practical.

The softness turns painful when Caelum notices Dahee's coping habit. Dahee insists she is fine, but her body tells the truth before she does.

Evening darkens the archive. The pages, altar rule, and Dahee's status as an outsider all point toward one conclusion: she may be the loophole the story wants.

Caelum rejects Dahee's sacrifice with more emotion than she has ever seen from him. His control cracks not from anger at her, but terror of the story using her kindness against her.

The argument cools into a terrible alternative. Caelum proposes a way to deny the rule its structure: no sacrifice left behind, no duke freed by another person's death.

In the locked apothecary, Caelum retrieves a single poison vial. Dahee understands the plan fully: two cups, one vial divided between them, one midnight.

Dahee and Caelum prepare the cups. The scene is quiet and intimate, framed less like suicide and more like two prisoners making a desperate pact against the story's terms.

Dahee and Caelum carry the cups through the silent castle. Servants are absent. The halls feel like the world is holding its breath as midnight approaches.

On the balcony above the black gardens, the air is cold and moonlit. The clock tower is visible in the distance. The moment becomes tender because both of them know it might be the last unscripted thing they ever do.

The balcony kiss becomes the chapter's emotional peak. Dahee drinks first before Caelum can hesitate or stop her. The clock begins to strike midnight as he raises his cup.
