I finished it a couple of days ago. I have to say, in the beginning, I kinda loved it since it is a sweet drama without a dark plot or something like this. Indeed, the couple is in a relationship in episode 5 or 6 I think, pretty fast but ain't complaining cause I loved them. After the first half, things got weird and the writers wanted to do it a bit dramatic. Honestly, I didn't enjoy the last 3 episodes. Only nonsense for me. I mean, why An Ning was so sad? For what? She should have analyzed everything much better.
The main couple was so sweet, crazy in love, and with many sweet moments. About the second couple, honestly, I don't know, I skipped almost all their scenes since I was used with Marius Wang on The Untamed. The drama was okay, but as I said, the end made it horrible and with nonsense and many cringe moments. If you don't have what to watch, you should try this.
