As tvN’s Saturday-Sunday drama 100 Days of Deception continues to captivate audiences with its gripping espionage action set in Gyeongseong during the Japanese colonial period, both its ratings and popularity have been gaining momentum. Amid the dramatic twists and heartbreaking romance in the series, actress Park Jung Yeon’s family background has also attracted considerable attention.
In 100 Days of Deception, Park Jung Yeon plays Kim Myeong Nam, the only daughter of Kim Seung Eok (Lee Ki Young), a powerful pro-Japanese collaborator who owns Joil Textile and has even been granted a marquis title.

Although Kim Myeong Nam enjoys the luxurious lifestyle of a modern woman, she is deeply ashamed of her father’s collaboration with the Japanese authorities. Behind his back, she secretly provides financial support to Gugukdan, an underground independence movement organization, and helps fellow activists who find themselves in danger. This makes her a complex character with many layers.
Despite the differences in their social status and circumstances, Myeong Nam also harbors undeniable romantic feelings for Lee Yeong Bok (Lee Seon), who has devoted himself to the independence movement. In a recent episode, after Yeong Bok was wounded by gunfire from Japanese police, she hid him in a secret room, personally stopping his bleeding and nursing him back to health. With tears in her eyes, she told him, “Don’t die, Yeong Bok. If you die, I’ll fire you.”
Later, Yeong Bok discovered a message Myeong Nam had written on the bandage wrapped around his wound: “Don’t die. No matter what.” The emotional moment deeply moved viewers and left a lasting impression.
Park Jung Yeon has been delivering a nuanced performance as Kim Myeong Nam, a woman constantly walking a dangerous tightrope between the cause of Korean independence and her father’s watchful eye. She skillfully portrays the character’s complicated emotions as she navigates life under the oppressive circumstances of the era.
Her ability to switch between two contrasting sides of the character has also been praised. In front of her father, she uses an innocent smile and playful affection to avoid suspicion. However, when she is with her fellow activists, she reveals a cold, unwavering determination, adding tension to the drama.
As her compelling performance continues to draw attention, Park Jung Yeon’s family background has also become a hot topic. Born in 1997, she is the second daughter of Park Hak Ki, a legendary figure in Korean folk music, and actress Song Geum Ran, who played the second incarnation of Daily in the popular 1980s children’s sci-fi tokusatsu film Wuroimae From Outer Space 2.
Her older sister is also actress Park Seung Yeon, a former member of the girl group Matilda. In other words, Park Jung Yeon comes from a family deeply rooted in the Korean entertainment industry.

As a child, Park Jung Yeon appeared alongside her father, Park Hak Ki, on KBS programs such as You Hee Yeol’s Sketchbook, where her bright, refreshing beauty helped her become familiar to audiences at an early age.
She later trained under SM Entertainment as an SM Rookies member before officially beginning her acting career with the 2020 tvN drama Hi Bye, Mama!. Last year, she earned recognition for her performances in the SBS drama The Winning Try and the KBS2 weekend series Our Golden Days. Her performances won her rookie awards from both terrestrial broadcasting networks, establishing her as a rising actress with leading-role potential.
Having joined Salt Entertainment, Park Jung Yeon took on her first historical drama with 100 Days of Deception, further expanding her range as an actress.
Viewers have noted that her solid acting skills, built through steadily accumulating experience rather than relying on her parents’ fame, are a perfect match for the weighty visual atmosphere characteristic of historical dramas.

With the burden of coming from a pro-Japanese family and the danger of secretly supporting the independence fighters of Gugukdan, audiences are eager to see how long Kim Myeong Nam can keep her double life hidden. Park Jung Yeon’s portrayal of a woman desperately trying to protect the person she loves while facing a cruel fate has emerged as one of the key elements to watch in the drama’s second half.
