NEED HELP FINDING A DRAMA

I'm trying to help someone on tumblr find a drama they have been looking for. If you have any ideas please tell me. Their description is below. Thank you!
"Do you know the name of the this mbc drama where this girl gets involved with a professor but he already has a wife (ji hyun) and daughter ( Ha na) ?"

@ Koreandramafeels - I think the drama that you're looking for is Great First Wives . I haven't watched this drama but based on your description, the wife's name is Ji Hyun/ Ji Yeon and a daughter named Ha Na. If you'll look at the cast it will fit.
