It begins with a flashback, revealing that Si Jiang lost his beloved son, but unexpectedly encountered the abandoned Zai Zhen in the place of his Khmer mistress.From this, the mystery of Zai Zhen's life experience is revealed - he is not Si Jiang's biological flesh and blood, but Si Jiang carries this secret and is deeply afraid of being known.

After a fight with Se Na, Young Won reveals the existence of the spy camera to Si Jiang.Sijiang immediately summoned the housekeeping staff and Secretary An, solemnly informed them about the spy camera, and told them to be highly vigilant against outsiders.Meanwhile, Dr. Oh personally visits Jae-jin at the clinic, hoping to win his favor by curing him.

On the other side, Yingyuan and Yongmin visited their mother together. During this period, Yingyuan confessed her heart and told how she worked hard to maintain the family's financial stability after her father passed away and worked hard to win the favor of the Cui family.She also revealed Se Na's threats to her to Yong-min, and the two then went to the police station responsible for investigating the fire in Se Na's childhood home.There, they were surprised to find that Officer Cha mentioned Se Na as the culprit of the arson many times, but the case was closed in a hurry without any further investigation.

Daoxian's girlfriend Su Yi visited Yingyuan in the office and frankly told her that she was pregnant with Daoxian's child, and expressed her desire to leave a child with Daoxian and live abroad.Su Yi implored Ying Yuan to communicate with her mother.After Yingyuan told Si Jiang about the incident, Si Jiang immediately rushed to the clinic to tell Jae Jin the news and encouraged him to cheer up.Doctor Wu watched them leave anxiously.

Jae-jin returned home and had an in-depth conversation with his son, ultimately giving him unwavering support.At the same time, Dr. Wu's mental condition became increasingly unstable. She stared at the photos of the Cui family, cut and pasted herself into them, and fell into delusion.At this time, she received a text message from Taiwu, encouraging her to save Jae-jin.

Yingyuan and Sijiang were invited to meet Su Yi's mother, and Sijiang offered to use money as bait to persuade her to give up the child.Suey's mother seemed moved at first, but then left in anger because she felt humiliated.Sijiang immediately assigned Kang Cheng to investigate Su Yi's family background and found that Su Yi's family was in trouble after her father went bankrupt.

After the meeting, Young-won, Kyung-min, and Seung-jae visited Officer Cha, who now runs the deer farm.Officer Cha revealed to them that Se Na's sister narrowly escaped the fire, but news of her death spread before she recovered.She once identified Se Na as the arsonist to Officer Cha. However, before Officer Cha took action, Se Na had been adopted by a family in Norway, and the case was dropped.Officer Cha also provided Ying-won with Se-na’s address in Norway.

Young-won returns home and finds Do-hyun glaring at her, asking her if she would give money in exchange for an abortion.It turned out that Sue's family left a guarantee letter stating the transaction.At the same time, Young-won's mother also angrily came to Si Jiang and asked her not to interfere in her son's affairs, insisting that she would educate Do Hyun in a completely different way from how Si Jiang raised Jae Jin.However, after some communication, she finally expressed to Daoxian that she would fully support his decision, and the relationship between mother and son was restored.

Young-won goes to the monastery to find Se-na's sister in order to uncover more truth.The scene then cuts to an interview in which Young-won reveals the shocking truth about Se-na’s crime.She sent the recording of the interview to Se Na and threatened that if she wanted to prevent the recording from becoming public, she would have to meet her in person at the broadcast studio.Se Na hurriedly came to find her sister, but was told: “This is all lies, your sister has passed away long ago.”In anger, Se Na pinched Yingyuan's neck tightly.
