Trivia / The Heirs

• Dawson Casting: Every teenage character in the series is played by an actor several years older than a high school student ought to be. At 19, only Bo-na (Krystal Jung) is technically still a teenager in the cast. Tan's actor, Lee Min-ho, is the worst at 26. He's actually a year older than his on-screen senior, Hyo-shin (Kang Ha-neul), and a year younger than Won (Choi Jin-hyuk), despite the fact that the latter is canonically about ten years his senior.
