This was the first Chinese anime I ever watched til the end. I initially dropped it after the first 2 episodes but seeing how the corona virus has caused a lot of delays in other animes, I decided to pick it up again because I was looking for something to watch and I remembered that it was quite funny. But as the anime progressed, the story started to get more interesting. The villainess started to get increasingly sly with her plans to drag Qin Ya down, to the point where I honestly hated her guts (a sign of a villainess done well). It was enjoyableto see the characters grow, especially Qin Ze, although the romance seemed a little rushed.
Like the previous review mentioned, the ending did seem rushed but overall I did enjoy the story. Even though its far-fetched for opposite sex twins to switch places unnoticed (especially when one of them is an idol), the plot still seemed quite realistic with all the ploys happening within the entertainment industry; which I found is what made the anime interesting.
And last but certainly not least, the songs were incredible! The anime portrayed Qin Ze as having a strong passion for music, and I think the singer was able to deliver that perfectly with his stunning vocals.

Overall, I'd say if you're looking for a music/idol anime with a touch of reality and romance in it, then this anime might just be your thing :)
