This was a great high school drama, like the ones that made you feel like you wanted to be in high school again. I love the friendships in this story, it made the show enjoyable and easy to watch. There was a second male lead, but he wasn't annoying. The leads had a healthy relationship, and the friendships in this story were just the icing on the cake. And in the end, I really did for the characters, but that being said I did not like the structure of the show.
I personally like stories that have a plot throughout the show and the conflict is presented midpoint and so on. But in this show, they resolved the main conflict of the show at the midpoint of the series. And after that, it just felt like a bunch of filler episodes. I think this series would have been better if was about 12 to 18 episodes long. I thought it was too long, not to say that it dragged, but you could tell the writer was just adding things in to fit the episode requirement. It was still a good show, but it had a bunch of subplots, which I can't say I enjoyed too much. About every 6 episodes or so was a different subplot, if you enjoy shows like these you'll probably like this one. But I prefer a show with continuity rather than a series that is broken up. It felt like a compilation of high school stories, which is not a bad thing it is just not for me.
I will say after a while I lost interest in the main couple and started liking the second couple and the boy best friends better. The only regret I have with this show is that they did not expand on the storyline of the boy best friends. I know this is due to censorship laws in China, but their story could have been great.
Overall if you want to watch a few stories of high school figuring it out while laughing along the way, this would be the series for you.
