I wouldn't expect this kind of drama to have a sad ending, so I still think it will be a happy ending.. but based on some preview I saw..if hee joo survives, the real sa eon will probably survive as well..
I've watched 7 episodes but i feel like the initial story could've been wrapped up in like 6.. but anyways I wonder what the rest is going to be about.. probably getting the approval of the male leads parents or something
