My Royal Nemesis co-stars Lim Ji-yeon and Heo Nam-joon offered a glimpse into their close working relationship in a newly released preview for You Quiz on the Block.

During the interview, Lim Ji-yeon explained that romantic comedies depend heavily on the chemistry between the lead actors and felt strongly that both performers needed to showcase their strengths for the story to succeed. “In a romantic comedy, both actors’ charms need to come across for the drama to work. Heo Nam-joon is such a charming actor, and I really wanted that to be reflected well in the drama,” she shared.

Lim Ji-yeon went on to describe how fortunate she felt to have found a co-star with whom she could communicate openly and comfortably. According to the actress, the demanding filming schedule and the pressure of carrying a leading role sometimes left her physically and emotionally exhausted. “There were many moments when the heavy responsibility and large amount of screen time made me feel overwhelmed both mentally and physically,” she admitted.

Despite being the senior actor, Lim Ji-yeon said Heo Nam-joon consistently helped lift her spirits during difficult moments. “Every time I struggled, he encouraged me like a vitamin. Even though I’m the senior, I realized how much I relied on him. I often thought, ‘I’m so glad Cha Se-gye was played by Nam-joon.'” Her comments highlighted the close bond the pair developed while working together.

Heo Nam-joon also spoke warmly about Lim Ji Yeon and their on-set chemistry. The actor revealed that they often joked about who deserved credit for creating the positive atmosphere on set. “We always joke that everything worked because of one of us,” he said with a laugh. However, Heo Nam-joon was quick to emphasize that much of the credit belongs to Lim Ji-yeon.

According to Heo Nam-joon, Lim Ji-yeon consistently maintained a positive attitude despite the demanding filming conditions. He praised her professionalism and kindness, noting that she rarely showed signs of fatigue even when she was exhausted from long shooting schedules. “No matter how tired she was or how little sleep she got, she always tried to smile and take care of everyone around her.” The actor added that the comfortable and playful atmosphere on set would not have been possible without her willingness to engage with him and support their teamwork.

Lim Ji-yeon’s heartfelt comments have drawn attention from viewers who have enjoyed her chemistry with Heo Nam-joon in My Royal Nemesis. Fans are now looking forward to seeing the full conversation when she appears on You Quiz on the Block, where she is expected to discuss her career, current projects, and behind-the-scenes experiences in greater detail.
