K-dramas often rely on the dramatics of romantic relationships. While the main characters are always in the spotlight, the second leads also add to the charm. Interestingly, second leads in K-dramas are no longer just narrative accessories. Over the years, makers have chosen to give them more emotional depth, strong arcs and memorable screen presence. Some challenge the male lead, while others give more meaning to friendship and companionship. Sometimes, they quietly outshine the leads as well. Many linger long after the final episode ends.
