Hi, Sayaka, if either you or Mitchy doesn’t mind, can I answer to your question? I don’t think he could give you a proper answer given he’s not much interested in TV dramas and actors.^-^ It’s Lee Youngae (이영애) who was starred as 長今이-an informal name for the character, since the drama’s huge success, this name has become a general nickname for every girl who is a good cook-, and the woman on the advertising board is not her. I even wonder if she is really Korean because her appearance is not like what we would mostly expect from ‘after-surgery.’
