It's not so much about reconciliation between a divorced couple, but A Beautiful Life is rather similar in their exploration of relationships. The protagonists in both films are faced with problems that require love, patience and pure tenacity to be able to endure and overcome and that's probably what draws common ground between the two. Without giving away too much however, I guess you could say that A Beautiful life is also about reconciliation between a couple as there is at some point, a bump in their relationship.

Both involve a female protagonist travelling back in time. They also become involved with important historical figures of that time and contribute in politics/strategies using their knowledge from the future.
Splash Splash LOVE is definitely a lot shorter, but it's worth a watch if you want something quick and succinct.
