Korean Contemporary Romance is great. I recently watched "That Winter, The Wind Blows". The story revolves around a con artist who makes a very wealthy blind woman believe that he is her long lost brother. She has no other family and lives in a huge mansion with all her servants, so no one has proof that he is not telling the truth.
His keeping this secret in order to pay off very scary loan sharks and their eventual love blossoming is what this show is about.
