In 2013, South Korean broadcaster SBS premiered "The Heirs," which remains a well-loved show among K-drama fans even after many years since its release.

Penned by star screenwriter Kim Eun-sook, "The Heirs" — which aired in the Philippines via ABS-CBN — follows the romance between Kim Tan (played by Lee Min-ho), the heir to a Korean conglomerate, and Cha Eun-sang, a girl who takes on part-time jobs to support herself and her mother. Their story is mostly set in a prestigious high school for the wealthy, where Eun-sang manages to get a scholarship.

"The Heirs" has all the elements of a classic K-drama: the love story of a well-off and poor character, and storylines relating to family and friendship. But another reason behind the show's enduring appeal is its stellar cast, with most of the supporting actors going on to becoming popular stars in Korea's entertainment industry today.

Below, we catch up on the stars of "The Heirs" and their recent projects.

Lee Min-ho

Lee was already a popular actor before starring in "The Heirs," having appeared in hit dramas like "Boys Over Flowers" and "City Hunter." In the teen series, he plays Kim Tan, the son of a conglomerate president to his mistress.

At a press conference in Manila last October, Lee — whose other notable shows are "The Legend of the Blue Sea" and "The King: Eternal Monarch" — said his upcoming projects include the second season of "Pachinko" and another drama.
