Perfect Family’s sixth episode begins with Jin-hyeok encountering his mother’s butlerr. The man speaks with Jin-hyeok regarding Sun-hui appearing at their house and requests him to prevent her. Jin-hyeok expresses regret for worrying his mother. The steward departs after cautioning Jin-hyeok about a potential life-changing car crash.
Jin-hyeok departs after the secretive gathering concludes, heading home. The scene transitions to Sun-hui in her bedroom where she searches for details on the fire Hyun-min mentioned using her computer. At that moment, Eun-joo arrives at her room. Sun-hui attempts to divert her mother’s attention by shutting the computer screen, while Eun-joo observes Sun-hui’s actions through the reflection in the window. She inquires if Sun-hui would like to eat some porridge.
That evening, Hyun-woo arrives to see Sun-hui, but Eun-joo blocks him from meeting her. Hyun-woo becomes worried about Sun-hui and goes to the police station to inform them about the car accident and Soo-yeon going missing. At home, Sun-hui listens in on Eun-joo’s conversation with Jin-hyeok, where she declares her desire to harm “them”.
Sun-hui enters the kitchen and discovers peanut powder. Aware of Sun-hui’s life-threatening peanut allergy, which has caused her near-death experiences in the past, she becomes terrified that her mother is trying to harm her. At the police station, Hyun-woo meets Dong-ho and informs him about the crimes. Upon departing the station, he reaches out to Sun-hui, seeking her forgiveness through a message.
Eun-joo gives Sun-hui porridge with peanut powder, but Sun-hui becomes scared and tosses the spoon. Sun-hui angrily leaves the house and begins to run on the street. Near the post office she conceals herself and informs Hyun-woo of her location. Hyun-woo tells Sun-hui to wait, but Sun-hui attempts to cross the street along with a group of other pedestrians.
Nevertheless, a man wearing a black raincoat shoves Sun-hui onto the road and she gets struck by a vehicle. The ambulance is summoned and Sun-hui is transported to the hospital. Hyun-woo gets to the street and runs after a man he recognizes as he drives away in a taxi. He questions Sun-hui’s whereabouts when he bumps into Jin-hyeok, who is dressed in a black raincoat resembling the one worn by the man who shoved Sun-hui.
At that moment, Jin-hyeok receives a phone call from the hospital and quickly goes there with Eun-joo. Hyun-woo meets them at the hospital and they find out Sun-hui was unconscious because of the accident.
While in a state of unconsciousness, Sun-hui experiences hallucinations in which she envisions Eun-joo attempting to strangle and murder her. Jin-hyeok is requested to speak with the police who inform him that Sun-hui was shoved into the street causing her to collide with the car. Jin-hyeok seems incredibly indifferent towards the comment.
At that moment, Hyun-woo quickly goes to get Jin-hyeok from upstairs, saying that Sun-hui has woken up and is yelling. Eun-joo and Hyun-woo work together to soothe her. Sun-hui shoves Eun-joo aside and informs Hyun-woo that her parents are attempting to murder her.
The police officers waiting outside attempt to rouse Sun-hui and gather additional information about the statement, but the medicine given by the doctors causes Sun-hui to lose consciousness once more. Sung-woo informs Dong-ho that Soo-yeon was spotted near Kyeong-ho’s residence during the fire. He also mentions that, because Jin-hyeok was a respected lawyer, they had no means of obtaining his dashcam footage.
They come up with a scheme and recruit a just-released ex-convict to intentionally crash into Jin-hyeok’s car. After the car is brought in for repairs, the police enlist the assistance of the forensic team to search for any evidence implicating Jin-hyeok.
The morning after, Sun-hui wakes up to a horrific vision of Soo-yeon accusing her of causing her own demise. Eun-joo awakens beside Sun-hui in the hospital, urging her to take a break.
Upon finding herself alone, Sun-hui quickly phones Hyun-min and requests his assistance. Hyun-min guarantees he will see Sun-hui shortly. At the same time, he reviews the footage from Jin-hyeok’s dash cam, which unmistakably captures Soo-yeon fleeing from his car on the night she went missing. In the hospital, Hyun-woo dials Soo-yeon’s number and requests a meeting with her.
A scene from the past depicts Soo-yeon getting into a taxi wearing a black raincoat shortly after Sun-hui’s accident. On the other hand, the police find nothing in the dashcam and determine that Jin-hyeok had just replaced the camera’s memory card. During the inquiry, it was discovered that Jin-hyeok’s vehicle contained remnants of human blood. The following day, Sun-hui is discharged from the hospital.
On their way home, Jin-hyeok questions Sun-hui about whether she is keeping something from them and inquires why she mentioned them wanting to harm her. Upon arriving home, Jin-hyeok is immediately arrested by the police. Jin-hyeok is placed in handcuffs and escorted to the police station. As he leaves, he reassures Sun-hui that he will be fine and asks Eun-joo to look after their daughter.
In the conclusion, Jin-hyeok is seen putting a lot of effort into ensuring Sun-hui’s happiness since she was adopted by him and Eun-joo before the episode concludes.
This drama just really confuses me a lot. Like what is really happening? Who should we suspect more?
