One of the most popular genres in Kdrama, aside from romantic-comedies, are the ones that feature strong male leads.
These types of lead stars often showcase the bad boy material but a softie on the inside, especially with their love interest.
They typically swoon the female leads with their confidence, dominance, and assertiveness, which is basically the opposite of a true gentleman.
Despite their strong personality, most of the time, women chose the bad boys over the boy-next-door type of person.
Although the year offered a variety of high-quality shows, from tv shows to films, here's a rundown of five 2021 Kdramas with badass male leads that would definitely make our hearts flutter.
