Actors Lee Seo Jin and UEE attended the press conference for their upcoming MBC drama 'Marriage Contract' on March 3 where they talked about working together despite the 18-year age difference.

Lee Seo Jin said, "The age difference does not matter.  UEE is young, but she puts in a lot of effort and our synergy is gradually matching up well.  The ambience on set is extremely good.  I'm extremely satisfied with the set."

UEE likewise said, "After Lee Seo Jin was cast, I was the second one to be cast.  I was very happy.  He doesn't like it when I say this, but I'm very happy on set and satisfied," adding that he would give her advice when she's having a hard time.  Wait, what doesn't he like?
