This drama is of the "divorce redemption" genre. Jang Na Ra (who is as doll-like and ageless as ever in this) plays Ma Jin Joo, mother of a son and wife of Son Ho Jun's Choi Ban Do, both of whom are nearing 40. Their marriage has fallen into a contentious state and the show opens up with a handful of events leading to their acrimonious divorce. After they both throw away their wedding rings, they wake up the next morning to find their 38-year-old minds in the bodies of their 20-year-old selves. They each set about trying to reshape their fates with the ones who got away.The second lead syndrome is strong in this show, as both Band Do's first love (ballerina Min Seo Young (played by Go Bo Gyeol)) and Jin Joo's sunbae (Jung Nam Gil (played by Jang Ki Yong)) do wonderful jobs presenting possible alternatives that absolutely fit and make sense and would be wonderful. The ever wonderful Kim Mi Kyung plays Jin Joo's mother, Go Eun Sook, and along with the rest of the supporting characters add nice flavor to the stew. The drama is only 12 episodes long and it's a rambling walk up until the last three episodes, where it suddenly sprints. Bring tissues. There are many feels.
