The SBS K-Drama My Royal Nemesis concluded its broadcast with a peak viewership rating of 11.8% in Korea, driven largely by the intense on-screen chemistry between lead actors Heo Nam Jun and Lim Ji Yeon. According to director Han Tae Seop, the real-life chemistry between Lim Ji Yeon and Heo Nam Jun was so strong that they had to actually tone it down for drama.
Why does on-screen chemistry impact K-Drama success?
Success in the competitive K-Drama market is linked to the chemistry of the lead actors. My Royal Nemesis serves as a recent case study, topping Netflix charts and exceeding domestic viewership expectations.

In the case of My Royal Nemesis, director Han noted that even a simple two-shot created a romantic atmosphere—to the point where it was actually difficult to gauge the right level of intensity.
How do directors manage actor tension on set?

What is the future of audience engagement in K-Dramas?
