Where the Story Left Off?
In the previous episode, Ga Kyeong interpreted during the interrogation of the newly captured Geum Seok Joong. The violence she witnessed, along with chilling threats from Fukuda, pushed her to quit being a spy. She packed up and left despite warnings that traitors would be eliminated.
The episode ended on a tense cliffhanger as Yoo Philip approached her with a gun hidden behind his back.
What to Expect in the Next Episode?
Ga Kyeong’s story takes a surprising turn. The preview reveals two parallel assignments:
- Her mission: Yoo So Ran assigns Ga Kyeong to win Sato Hideo’s heart.
- His mission: Sato Shinichi instructs Sato Hideo to gain Ga Kyeong’s trust.
Under all that pressure, the two share a charged moment, locking eyes at close range with neither looking away. Another set of stills shows Ga Kyeong startled as Hideo reaches out to grab her.
The production team says Ga Kyeong has reached a critical turning point as a spy. They also hint at whether sincerity can repair a bond tangled in lies and suspicion.
Why This Drama Is Worth Your Time?
Spy dramas thrive on double lives, and romance thrives on trust. Combining them means every glance carries two meanings: one for the mission and one for the heart. With both leads secretly assigned to charm each other, viewers are in for a tense, emotional ride.
While you wait, catch Kim You Jung in Dear X and Park Jinyoung in the film Hi-Five on Viki.
