I love K Dramas and have watched a ton of them, but unless they are Lee Je Hoon or Jang Na-ra, most of the time I'll refer to the actors/actresses as "ahjusshi yg selalu main jahat" or "pompuan yg pandai lawan tapi muka sweet gila" or "ala that guy yg I still can't believe is younger than me tu". I can't remember their names to save myself. Ingat muka je.
