Dr. Lu Yingyuan walked through the white snow and came to the hut where her mother-in-law Hong Sijiang lived.In this seemingly peaceful environment, the family hardships and twists and turns between her and her mother-in-law Hong Sijiang gradually surfaced through a series of short flashbacks, foreshadowing the coming storm.

Yingyuan, a high-profile psychiatrist, not only appears frequently on TV shows, but also maintains a seemingly perfect family.Her husband Choi Jae-jin, a successful surgeon, and the two are about to win an award for their outstanding performance.Her mother-in-law, Hong Sijiang, is a digital novelist who strives to gain popularity among readers.In addition, Yingyuan's father-in-law Choi Khmer, a former prosecutor, also plays an important role in the family.

However, the relationship between Khmer and Si Jiang appears to be extremely tense, and Si Jiang is even more difficult to get along with.After breakfast, Yingyuan hurried to the workplace.Her schedule is already packed, but despite this, she still emphasizes work-life balance.

At this time, a new patient named Li Shina walked into Yingyuan's clinic.She confided to Yingyuan her painful experience of falling in love with a married man, and the helplessness of a man who had to continue to maintain a marriage in order to maintain the superficial harmony of the family.This scene made Yingyuan feel uneasy, and Se Na directly questioned whether Yingyuan knew everything about her family.In response, Yingyuan could only reply helplessly that no one can fully understand his family.

The next day, the family went to church, and Yingyuan became the center of attention.Later, when Jae Jin sent his son Choi Do Hyun to school, the two talked about Do Hyun's love life and his mother's controlling nature.Back in Yingyuan's office, her brother Nuo Yingmin suddenly came to visit.It seems that he quit his job again and hopes to start a business with Yingyuan and let Yingyuan provide consulting services.However, Ying-won did not agree to his proposal and soon kicked him out of the office.

At this moment, a beautifully wrapped gift was delivered to Yingyuan's office.When she carefully opened it, she was stunned by what she saw - a beheaded bird, photos of her family, and a chilling question: How is your family?“This incident made Yingyuan feel extremely uneasy, and she began to wonder whether her family was facing some unknown threat.

Recalling my father’s teachings: ” Yingyuan, life is not always so smooth.You may fail, and sometimes you may slip up like you just did.Life has its ups and downs and that's how people become resilient.% Yingyuan made up her mind that no matter how difficult she faced, she would not give up easily.

Meanwhile, Jae-jin develops symptoms of panic disorder after surgery and is comforted by his colleague Dr. Oh Ji-eun.However, when the surgical team went to have lunch, Jae-jin unexpectedly met an old acquaintance - Wen Tae-oh.The two chatted happily and left the restaurant together, which made Dr. Wu very frustrated.In another corner of the restaurant, Yingyuan was having lunch with her team.When Jaejin introduced Taiwu to Yingyuan, Yingyuan thought this person was a bit strange.

On the other side, Sijiang visited a designer to choose clothes for the award ceremony.However, she was displeased when the designer praised Young-won instead of Jae-jin.Later, Sijiang stumbles upon an old-fashioned mainland restaurant and reveals that he may have an unknown past with chef Park Kang-sung.

Just as Yingyuan was driving back to work from the restaurant, she suddenly received a call from her manager.It turns out that a video about her father's suicide is going viral on the Internet.It was revealed in the video that her father had been accused of corruption and sexual assault, and what was even more shocking was that her father had been friends with Jae Jin's father, but the latter refused to help him at the critical moment.Recalling her high school days, Yingyuan once asked her father to protect her family and prove her innocence. However, her father chose to end her life by jumping off a building.

This news made Yingyuan feel heartbroken, and Khmer also saw the video.He invited Zai Zhen to have a drink and talk, but Si Jiang suddenly got involved.Zai Zhen decided to eavesdrop on his parents' conversation to learn the truth, but unexpectedly discovered the cracks in their marriage - it turned out that the relationship between Si Jiang and Khmer had long been in name only, and Khmer's multiple derailments made Si Jiang feel discouraged.In the end, Khmer chose to leave the family, leaving Sijiang to bear the pressure of life alone.

The next morning, Khmer accidentally slipped and fell while walking his dog and was injured, unable to move.However, fate seemed to be unforgiving to him - a boulder slid down and hit him, taking away his life.Yingyuan was shocked and saddened when she received the bad news. She could not accept this cruel reality.

In the funeral home, Yingyuan unexpectedly met her patient Se Na.Se Na cried so hard that she seemed very sad about Khmer's death.Based on their previous conversation at the clinic, Young-won suspects that Se-na may have fallen in love with Khmer.This discovery made Yingyuan feel even more confused and uneasy.

After returning to Cui's house, Young-won discovered a hidden safe in Khmer's former room.When she opened it, she found a notebook and a USB flash drive.While browsing the contents of the USB drive, she was shocked to discover a recording - a recording that proved her father's innocence and that Khmer was one of the people who made her father a scapegoat.
