On this day, No Ki-jun was thrown into confusion after witnessing Joo Won-a's secret private life. While No Ki-jun tried hard to keep his distance, Joo Won-a remained calm as if nothing had happened. However, the strange tension flowing between them hinted at a shift in emotions.
Then, a turning point arrived, igniting a spark of feelings neither of them knew they had. Joo Won-a and No Ki-jun went out on an assignment to investigate allegations of targeted audits at the main research institute of Haemu Group. Joo Won-a immediately recognized someone as a target of an audit, while No Ki-jun calmly persuaded the trembling interviewee. Their collaboration, befitting an ace duo, was flawless.
Lurking behind the incident was an extraordinary figure. They noticed something unusual in the corporate card records of James (played by David), the key CTO of Haemu Electronics, whom Jeon Jae-yeol (played by Kim Jae-wook), the executive vice president, had carefully recruited. Joo Won-a casually mingled with James and quietly gathered the necessary information. Since James was a key figure in the company, digging too deep too soon could have put them in a difficult situation. To secure concrete evidence, Joo Won-a and No Ki-jun conducted a secret undercover investigation at the hotel where James headed that night.
Pretending to be a couple to infiltrate the hotel, Joo Won-a and No Ki-jun were momentarily flustered by the romantic event decorations prepared by the hotel. After a brief awkward atmosphere, as the two became slightly tipsy on champagne, their toes lightly brushed, exchanging a strange current. As they continued their playful bickering, they ended up embracing and collapsing onto the bed. The intense eye contact from a distance where one could almost hear each other's heartbeats made the hearts of viewers race.
The hotel infiltration operation was successfully concluded. It seemed the case was settled when they suddenly raided the scene just before James summoned a subordinate to the hotel to apply pressure. However, a sharp confrontation unfolded between Jeon Jae-yeol, who had personally brought James, and Joo Won-a. No Ki-jun silently used a clip to fix Joo Won-a's disheveled shirt after she emerged from the vice president's office, but the inexplicable atmosphere flowing between the vice president and Joo Won-a bothered him. The next day, seeing Joo Won-a smiling brightly while placing that clip in Ki-jun's hair, No Ki-jun also found himself smiling for no reason.
Another submission email arrived for No Ki-jun, and upon seeing a photo of Joo Won-a embracing a mysterious man in the underground parking lot, No Ki-jun turned cold. The dizzying moment in the hotel room and Joo Won-a's bright smile kept flashing in his mind, and he felt the need to confirm his own feelings. No Ki-jun returned to the art academy, sat quietly in front of an empty easel, and began to paint Joo Won-a for the first time without any prejudice or hatred. The two faced the completed painting. The intense eye contact that followed the words "You're pretty," and the passionate kiss ending raised heart rates, promising a new chapter.
tvN's Saturday-Sunday drama "Secret Gratitude" airs every Saturday and Sunday at 9:10 p.m.
