I like films or series that has underlining messages for humanity. Cute and enlightening, the idea is entertaining about going back and trying to “fix things”.but of course since this is not possible “yet”, this series prove that no matter what you do, it is never a 100% proof.
My interpretation that don’t live your life in a “what if” mode. Don’t regret what you do because in that moment when you decide, it’s the best decision you make.
