The story's momentum does not pause and that is what makes it interesting to watch. Unlike in any other Cdramas, here you'll find a very cheerful male lead (but for a certain period of time). The revealing/ discovering of secrets and new things are well portrayed. I'll give it 7/10 for story and screenplay.
But, nothing in this universe is perfect. That being said, let me tell you beforehand that female lead looks wayyyy older than the male lead. I think they should've casted someone who looks younger or equals to Yibo. I said this because most of the audience are very much used to seeing matching couples on Asian dramas. Female lead, to me, sometime feels like Yibo's elder sister. The chemistry how much ever tried, looks dry because of the visible age gap.
So if you are looking for chemistry, there is a very rare chance for it to be in your liking.
