A perfect rom com, done right in every aspect and exactly what I needed at the moment.
At first glance it may look like any other time travel light hearted rom com but no, the characters are unpredictable and the dialogues/conversations are very funny. Even the most serious moment had me cracking. Because there were situations that were so relatable. I don't know how to explain it but it's like watching the sitcom FRIENDS. A good laugh through out the entire series with interesting plot. The comedic part didn't feel force.

The supporting characters were actually very good. They didn't feel like filler or irrelevant.
Bai ji and zi rui stole the show for me to be honest.

Also the lead characters had amazing chemistry.
Ding yuxi isn't exactly the eye candy 10/10 perfect man you see in a lot of youth drama. But in some way he is very attractive and his expression are also very good. He instantly became one of my favourite actor.
As for zhao lusi I think this is her best drama so far,though I would love to see her in more serious role.

As for the story of course some part of it makes less sense, but them being inside a script made it proper and I didn't find myself questioning anything.

The soundtrack were okay, not that memorable.

Overall a very good watch, from episode 1-24,there wasn't a single boring moment.
My only complain would be wishing it had one more episode, so that the meeting in modern world wasn't as rushed as it was. It felt a bit less satisfying and left me wishing for more.
