Luo Su Resigns and Departs for Taiyuan
Luo Su officially visits County Magistrate Han Mozhi to tender her resignation from the Linfen yamen. Although Han Mozhi attempts to hold her back by asking whether her sudden departure stems from his arranged engagement to Liu Wan, Luo Su makes her independent stance clear.

"I want to step out into the world on my own terms." — Luo Su
Han Mozhi then turns to Liu Wan to question her role in Luo Su's decision. Liu Wan confronts his underlying selfishness without hesitation, pointing out that keeping Luo Su nearby without giving her legitimate standing or autonomy is pure possessiveness rather than care.

"Are you really going to act this selfishly?" — Liu Wan
Having obtained her formal release documents, Luo Su heads to the Mingke brothel with silver in hand to ask her closest confidante, Jin Miaocui, to leave Linfen with her. Instead of celebrating, Miaocui pushes her away with an urgent warning.

"Do not return to Taiyuan, and trust no one. Trust only yourself." — Jin Miaocui
Meanwhile, Qi Menglin faces constant pressure from his family to return home. Worried that Luo Su might spend the New Year holiday alone in Linfen, he plans to stay behind until he learns she is traveling to Taiyuan. Seizing the opportunity, he packs his bags and joins her journey.

"That worked out well. We are heading in the same direction." — Qi Menglin
Upon reaching the crowded city of Taiyuan where the inns are fully booked, Qi Menglin accommodates Luo Su at his personal residence.

Conflicting Vows and the Imperial Threat Over the Qi Residence
The sharp contrast between Han Mozhi and Qi Menglin becomes unmistakable when they discuss Luo Su's future. Qi Menglin refuses to weigh family standing or bureaucratic status, openly declaring his resolve to take Luo Su as his lawful wife.

"I will marry Luo Su openly and honorably. She is the only woman I will take as my wife." — Qi Menglin
Han Mozhi questions whether Qi Menglin can protect her without the shield of his household. The question carries immediate weight as trouble gathers at the Qi Governor Mansion in Taiyuan.

"The imperial court has drawn its blade." — Qi Family Eldest Brother
A confidential message from Minister Hu reveals that the central court intends to investigate regional monopolies in the salt and iron trade, directly targeting the Qi family's financial base. Yet Qi Menglin's second brother dismisses the threat, accepting rare gifts and a mutton-fat white jade crescent ornament from local merchants.

"We have to accept their gifts so they can put their minds at ease." — Qi Menglin's Second Brother
While his family engages in risky political dealings, Qi Menglin remains focused on protecting Luo Su from uncomfortable social scrutiny, stepping in to drink penalty wine on her behalf during gatherings at the estate.

"I will drink this for her." — Qi Menglin
The Ending Reveal: Who Is Yulan?
The closing moments of the episode deliver an unexpected confrontation during Luo Su's morning walk through Taiyuan. An unfamiliar figure steps forward and speaks to her with surprising familiarity.

"Yulan, if you were coming to Taiyuan, why did you not send word?" — Mysterious Stranger
This greeting shatters Luo Su's composure. She was known as Jinlang during her time at the entertainment house and as Luo Su during her service at the magistrate office. The name Yulan points to her sealed childhood before the fatal fire that took her family.
