Can you guys help my friend? She's trying to find a Korean drama she just watched on a whim, but she can't remember the title, or the actors.

What she knows is that there is a woman whose husband is presumed to be dead, and she moves into the house of the male lead. The marriage with her husband was not what his family wanted, so when he died she was told to leave. The main lead and the woman fall in love but the husband comes back (he's not dead), and demands she comes out of his house. 

If it helps she says the male lead actor was muscly. 

She also *thinks* it was a long drama, approximately 50 episodes?

There's also a supporting role of some "really tall Korean actress" who "isn't the lead but is always being annoying and loud" with a "husky voice"

If this a drama she made up in her head then I'm going to have to contact a psychiatrist, so please help!! ^^

I tried googling and couldn't find anything, so if you do find out, let me know! 

Yes!! It is Legendary Witch, thank you all!!!!

You are most welcome. I know the feeling of not being able to find a drama you are looking for lol. Glad I could be of help :)
