The acting is decent and all costumes look good as well. I can't really judge the ost cause I watched on youtube and it was mute on important parts. so I'll go with 6 judging by the remains of it.
The first few episodes were a bit confusing, things were just happening out of nowhere, but then it got better after 4 or 5 episodes.

I'm glad each episode was less than 10 minutes or else I would've dropped it! There are so many unlikable characters! Being a short drama looks like it had the liberty of having the villains as vile as they could be.
Here is a list of horrible ones:
-The mother in law! & her maid!
-The ML
-Shang Guan
-Yu Yan's lover

it might make you feel better if I listed good characters, right?
-One maid is really good and loyal to FL, and I don't even remember her name!
-the guy with the maid, I don't remember his name either.
-2ML

The romance is so little that it gets lost in the fog of ruthlessness.
I can understand why this is listed in romance genre and I also understand those who have stated in the comments that this is no romance!
At the beginning we are actually as aware as the FL, meaning we only know what she knows. she got manipulated by Lu Gao Sheng thinking he loves her! until few episodes later that his vile self was revealed. from then on this drama is deprived of the romance. there is none. well, until 2ML appears but by the time he appeared FL is done with romance.

you bet I was looking forward to the REVENGE! but it wasn't as satisfying as expected.
In the end it wasn't about revenge. it was about saving her sister I guess.

it was an okay watch and I won't be re-watching it.

one more thing, If you are here for Dai Gao Zheng, he'll appear in ep17.
