I had only seen Lee Jun Ho as the polished, uptight hotelier in "King the Land" , where he played a very good part. However, in Rain or Shine (Just Between Lovers) he is superb as the "bad boy" , and classic "angry young man".
His "Granny" sees through the facade, and she, Na Moon Hee, is my second favourite actor in this programme.
Most of the main characters are complex - dealing with their own trauma from the past - and the actors portray their pain well.
I haven't finished this series, but, so far, it's been an emotional ride - with a little humour to balance out the tragedy.
