Goldmoss Post-house one week after the first ghost-stamped letter. Salt wind, dust, ledgers, and the imperial relay stamp frame Soyeon's ordinary pressure.

Soyeon processes ordinary mail while watching the magistrate's locked pouch, unable to stop investigating.

The ordinary relay stamp ignites, signaling a new ghost-stamped arrival.

The envelope arrives through relay-light, and Soyeon accepts it because refusal is fatal.

Soyeon opens the second ghost-letter and reads the first direct accusation.

The letter gives the title warning and threatens Soyeon's family if she flees.

Mira arrives with food and notices Soyeon's reaction, grounding the threat in family.

Mira identifies Yi by reputation, and Soyeon tries to act as if the question was casual.

After Mira leaves, Soyeon locks the letter away and rehearses silence as a bureaucratic weapon.

The next morning, the Goldmoss Watch arrives at the post-house door.

Captain Yi enters for the first time, composed and gentle, immediately contrasting the threat of the letter.

Soyeon refuses ordinary conversation and forces Yi into formal procedure.

Yi asks about ghost-mail incidents and reveals the magistrate's son has received something similar.

Soyeon gives a narrow technical answer about ghost-mail because silence would sound like ignorance.

Yi asks a technical question that reveals unexpected knowledge of clerk practice.

Yi mentions Jun's debt-bond as if it is ordinary public knowledge, rattling Soyeon's composure.

Yi makes a small considerate gesture while pressing the emotional opening he created.

Soyeon is drawn into asking about the ghost-mail incident despite intending silence.

Yi asks whether someone in the post-house could send ghost-mail backward, and Soyeon answers to prevent a worse misunderstanding.

Yi mentions a family-motivated stamp irregularity that points directly at Soyeon's old forgery for Jun.

Soyeon realizes refusing to answer will confirm what Yi suspects, so she bargains with information.

Yi leaves with formal grace, making the exchange feel intimate and dangerous.

Mira sees Yi depart and realizes Soyeon has done the one thing she meant not to do.

Soyeon reopens the drawer and the unchanged letter feels newly accusatory after the warning has been broken.
