Actually, this drama is a modern version of Maid's Revenge, according to official sources from her fan clubs, and when she referred to K2 at the airport, she did so in the sense that this time the series is based on her feelings about the protagonist and on how protective he is like a bodyguard but it was not fully understood but whatever it was, it will be a super drama and highly anticipated as well.

Thanks for your excellent comment! This drama is awful and when you say "And in that case, just watch the last three episodes or better yet, rewatch Maid's Revenge" you have all the reason.
