Yes all that math goes over my head but the story is genuinely heart warming with so many likeable characters.

Best part for me is the Dad in both worlds (with or with out that rock star hair) & if you love father daughter relationships this will definitely be a must watch.
Ep 1-9 were most people's favorite episodes because the kid actors are so good & darling, worth rewatching.
Ep 28-34 picked up at the end for a nice ending and a hint of romance

Few flaws:
After EP 10:
Adult Lin Zhao Xi didn't have the same tenacity other than a few scenes.
Cheese world Pei Zhi wasn't happy as his father described so definitely they should've matched the characters a bit better.

Overall a great drama out of the ordinary and might help you reflect on life & relationships.
