Park Jin-young Pieces Together Kim Yoo-jung's Secret After the Bomb in 100 Days of Lies

"Who am I supposed to call you, Ms. Geum Seo-hee? You're a spy, aren't you?" That line, delivered by Park Jin-young's Kim Tae-woong to Kim Yoo-jung's Lee Ga-kyeong, closed episode 10 of tvN's 20th anniversary special 100 Days of Lies, which aired on the 8th.

The episode picked up in the aftermath of the time bomb explosion, which set off a new chain of incidents. At the banquet, Sato Shinichi (Jin Seon-kyu) announced a cancellation and disappeared, leaving Kim Tae-woong alone just as news arrived that the prime minister had been attacked. Lee Ga-kyeong pushed a cake trolley into the way and pulled him to safety.

A fight in the elevator

Sato Shinichi headed for the governor-general's office. When the elevator doors opened on the fourth floor, someone held a knife to his throat: Song Jeon (Jeon Yung-beob), who had infiltrated the kitchen disguised as a cooking assistant. The two struggled violently, and Sato drove the knife into Song Jeon's chest. Asked who was behind the attack and whether the group Gugukdan was responsible, Song Jeon answered by shouting "Long live Korean independence."

Yoo So-ran (Kim Hyun-joo) had followed Sato upstairs to ambush him herself. Tracing a gunshot, she found Song Jeon bloodied on the floor and Kim Tae-woong standing over him with a gun. She misread the scene entirely.

Putting the clues together

Kim Tae-woong, meanwhile, went back over Lee Ga-kyeong's actions: the way she took his hand and led him away just before the bomb went off, and everything she had done up to that point. He concluded she was a member of the independence movement.

That sets up the final scene, in which he walks up to her and asks the question directly. It is a sharp turn for a character who has spent the drama on the other side of the story, and the quiet way the confrontation is framed leaves it open whether he intends to expose her or something else.

100 Days of Lies airs every Saturday and Sunday at 9:10 p.m. on tvN.
