Episode 17 recap: Song Huai Ning aroused suspicion in Lin Wen Yu.

Duan Xunchu Chu, heartbroken, confessed his feelings to Lin Wen Yu, but Lin Wen Yu, considering her identity as Duan Xunchu Chu's sister-in-law, drove him away. His departure also caused pain to Lin Wen Yu. Duan Xunchu Chu assured Lin Wen Yu that she would be treated well as his wife in the future, but Lin Wen Yu couldn't accept him and falsely claimed that she was not ready for the role of a wife yet.

Ignoring societal norms, Duan Xunchu Chu directly confessed his love to Lin Wen Yu, expressing his unwillingness to be just a brother-in-law. Lin Wen Yu, against her true feelings, claimed that she never liked him and heartlessly chased him away. Lin Wen Yu leaned against the wall, feeling heartbroken, while Duan Xunchu Chu remained at her door, refusing to leave.

Suddenly, Duan Xunchu Chu remembered something in his pocket. He recalled that his father had entrusted him with a purse during his childhood, which contained a yellow talisman. By chance, he discovered a hidden compartment in the purse that contained a map. He immediately asked Su Vice-Captain to locate the place based on the map.

In the middle of the night, Lin Wen Yu drank alone, and Huai Ning came with a wedding invitation, seeking her opinion. Lin Wen Yu casually chose one, and Su Huai Ning watched as Su Vice-Captain left, purposely asking Lin Wen Yu if she knew what it was about. This statement raised suspicion in Lin Wen Yu since he had inquired about it before.

When Song Huai Ning left, she secretly followed him and saw him meeting a servant. Using the excuse of delivering an invitation, Song Huai Ning returned to the Song family, and Lin Wen Yu accompanied him. Song Huai Ning intended to hold her hand, but Lin Wen Yu politely refused, stating that she was still not accustomed to their current relationship.

Song Huai Ning had a sudden headache and took medicine to drive away Lin Wen Yu. Su Vice-Captain investigated and discovered that Song Zhen Yuan had been lacking funds for a long time. Meanwhile, Lin Wen Yu called Duan Xunchu Chu and informed him that the president of the Fengcheng Chamber of Commerce was hosting a dinner tonight, and she wanted him to stall Song Zhen Yuan while she conducted an investigation at the Song family.

In the study at the Song family's residence, Lin Wen Yu searched for evidence and unintentionally discovered a key inside a lampshade. She used the key to open a box and found several letters.
