So the story overall was going okish. starting went a bit confusing as they swap time zone within one episode. Which was then again a good experience to see what is happening in 2012 and how things changed all of a sudden in 2024.
For all those who will watch and want to know spoiler things got better after episode 5 and the story stuck to one time zone from episode 10 onwards.. which was 2012.

Story went a bit drag but in the end went like ZOOM !! like the director or writer just had to finish things off asap. It was a happy ending but still feels incomplete from villain side. Like what happened Gao Ru Wen when he was strangling Lu Fan Fan. Just a guess that as police siren was going on in back he might have got arrested. But what happened to younger Gao Ru Wen who ran away with his father. There should have been a positive impact in future Gao Ru Wen too... maybe ... just own point of view.

So about the ending when Fan Fan getting strangled by Gao Ru Wen. Next scene was getting up in hospital in 2025. Figuring she travelled back to her time 1 year later which is 2025 finding out she was in coma for a year. And then the ending lit went like happy ending byebye take care y'all.

Overall, is it worth watching?! Would recommend if you don't have anything else to watch, go for it. The story was cute having twists, acting was pretty good too. Wouldn't say its a waste of time. But they could have made it better.
