Sungwoo got what was coming for him .though she did mention that she did not give him the he** she promised .and offcourse it's realistically speaking would give her marriage another chance...Kudos to author for such an ending...one need to work toward a relationship for it to be a success that what she showed us...but just that we all who feel bad for sungwoo for the whatever reason wanted him to be shown happy in his own world as well as a closure
