I'll start by saying I'm currently in a phase where I get really impatient with long, dragged out romance plots where it takes forever for the leads to get together. However, with this show even though they spend most of the drama not officially together I found myself not skipping a single scene because the interactions between all the characters were so precious and fun to watch.
I think all the characters had excellent chemistry with each other. Their friendships and journey through youth was really refreshing to watch and because the episodes were so short, they got to the point and it never felt dragged. Honestly, after watching this show I'm wondering why more youth dramas don't adopt this straightforward method of story-telling. It really keeps the content engaging.

I know a lot of people have been saying they like the second couple more than the main couple, but I actually disagree! Although I did love the second couple, nothing tops the main couple in this show for me. Their personalities are just so well matched and Su Zai Zai has to be my favorite lead girl. She's caring and sweet but also has a very straightforward, no-nonsense personality. A lot of classic drama tropes were turned on their heads in this show mainly because of how maturely she handled obstacles and I really respect her character for that. It shows that you don't have to be a cold and calculating type to be seen as a "strong" woman. Zai Zai was cute and affectionate while also being strong and I really appreciated that portrayal. Zhang LuRang was also portrayed very well and I think it's truly a "she fell first but he fell harder" type of relationship :)

In general, if you like romance and if you like light-hearted shows absolutely give this one a go. You won't be disappointed.
