This was the first C-Drama I ever watched. It wasn't "amazing", but it was good enough to keep me hooked.
By the end of the show, I felt like something was missing. It didn't fit as great as it should, mostly because of two things:
1. Hou Zi was WAY TOO GOOD for Xiao Yi, in every single sense. By the last third of the series you can't help it but feel bad for the guy... and kinda dislike Xiao Yi because all of her poor choices.
2. The ending feels rushed, not because viewers don't wanted Hou Zi and Xiao Yi to be together, but because writters wasted two whole episodes on Tian Fei and his CRAZY-OVERACTED mother. She was the worst part of the series, by far.
Tian Fei should have instantly died. We didn't need her mother's circus. I did't care for Lu's happy ending either, because neither her or Tain Fei had any redeeming qualities.

In general, the plot was nothing new, but good enough. The real problem was in the last few episodes.
