Obviously this is really long at 54 episodes, but there are several romances to keep viewers interested. The main story of the intelligent widower and strong-willed divorcee falling in love (office romance!) and working to combine their five children into one family is interesting on its own, especially their mistakes in figuring out discipline and support for the children in their blended family. But I also really enjoyed the secondary romance with Sung Hoon as the arrogant golfer who pursues the shy teacher. Two other couples provide additional romance to balance out the horrible, interfering, obnoxious in-laws who provide most of the conflict in the drama. For fans of realistic and healthy romance, this is definitely worth one watch!
