In the ninth episode of Perfect Family, Hyun-min informs Sun-hui that Jin-hyeok and Eun-joo had manipulated her adoption to make him a scapegoat for their son’s killing.
At the same time, Jin-hyeok and Eun-joo provide Dong-ho with a totally distinct account of the story. They inform the police officer that Hyun-min is the person who fatally stabbed Sang-woo and was responsible for their son’s death 12 years ago.
Jin-hyeok claims that Hyun-min, who had just been released from prison, was attempting to demand money from them. The couple reveals that Hyun-min abducted Sun-hui in order to demand more money from them. Jin-hyeok informs Dong-ho that Hyun-min attempted to blackmail him by asking for money in order to keep the secret of being Sun-hui’s real father hidden from her.
Eun-joo discloses that Hyun-min had proposed to tidy up the area where Kyeong-ho was killed in return for money after Sun-hui accidentally killed her friend. As she was leaving Kyeong-ho’s house with Sun-hui’s phone and textbook, Kyeong-ho’s parents came back. She says she attempted to contact the police but refrained when considering the possibility of Sun-hui being arrested.
The couple informed Dong-ho that Hyun-min had come to their home the day after the incident, demanding money to keep quiet about Sun-hui’s wrongdoing. Nevertheless, upon discovering that Soo-yeon was involved with Sun-hui, Hyun-min extended his offer to look after her too. Jin-hyeok states that Hyun-min took his car to chase after Soo-yeon, and Jin-hyeok had no choice but to allow it because he needed to save Sun-hui’s life.
He informs the police officer that he had made a decision to hire Hyun-min to safeguard Sun-hui and was ready to send her to Canada to help her escape the situation. Eun-joo admits that because she knew Hyun-min also had a peanut allergy, she had intended to contaminate his food in order to keep him from revealing the truth to Sun-hui. The pair inform Dong-ho that they can’t keep the secrets any longer and request the officer’s assistance.
In the meantime, Hyun-min becomes anxious as he waits for Jin-hyeok to arrive with the money, having kidnapped Sun-hui in a deserted building. He contacts Jin-hyeok, telling him not to play any tricks. The authorities have been notified and are currently stationed outside the building where Hyun-min had left Sun-hi.
The police catch Hyun-min’s friend but say they cannot harm Hyun-min until they determine the number of kidnappers present. Jin-hyeok volunteers to enter the building in order to rescue Sun-hui. Sun-hui, inside the deserted building, confides in Hyun-min about her faith in the individuals who took her in. Jin-hyeok arrives with the money and requests for Sun-hui to be released.
Hyun-min aims the gun at Sun-hui’s head and warns to end her life as retaliation against Jin-hyeok. Right before he can shoot Jin-hyeok, the police fire at Hyun-min and wound him. Sun-hui dashes towards Jin-hyeok but halts halfway to look back at Hyun-min. Hyun-min contacts Sun-hi once more and relocates to a safe place. Sun-hui stays by Hyun-min’s side and makes an effort to prevent him from bleeding excessively.
Hyun-min is surprised by Sun-hui’s actions and reminisces about all the happy moments they shared when she was younger. While Hyun-min contemplates his mistake, Jin-hyeok suddenly strikes him and attempts to grab his weapon. More shots are fired, causing Eun-joo and the police to be surprised. Jin-hyeok attempts to prevent Hyun-min from grabbing the gun, resulting in both men tumbling off the building and plunging into the ocean.
The police arrive to save Sun-hui while she sobs for her father in Eun-joo’s embrace. Another memory from Sun-hui’s youth depicts Hyun-min accompanying her to visit his mother’s home. He requests the elderly woman to look after herself while he is gone and leaves her there with a vow to come back soon.
Hyun-min squanders all his money due to his gambling habit. He was taken into custody for assaulting an intoxicated individual and attempting to steal his cash. He encounters Prosecutor Choi Hyun-min, who happens to be Jin-hyeok. Hyun-min attempts to make Jin-hyeok understand him by pointing out their shared names.
Jin-hyeok feels sorry for Hyun-min and decides to dismiss the case because there isn’t enough evidence to prove him guilty. Nonetheless, Hyun-min attempts to exploit his generosity and assaults him during an evening. He hits Jin-hyeok unconscious and steals from him.
In the epilogue, Dong-ho comes back home and has a video call with his son that night. He inquires with Dong-ho regarding his pet feline known as Princess. Dong-ho’s former wife requests him to cease communicating with their son as they are moving forward with their lives as the episode concludes.
The mystery is deepening. We still don’t know what’s really going on. Thank you for reading this recap.
