PLEASE READ BEFORE WATCHING!
There is sexual assault in this drama. I know many people are unable to watch that and its important to warn them about it.
This is such a hard drama to watch. I remember feeling the same way when reading the manga, Boys over Flowers, this is based off of. The male lead and main romantic interest, Dao Ming Si, is so difficult to root for. On multiple occasions he assaults the female lead, Shan Cai, threatens her, manipulates her, bullies her, and is an overall jerk. He shows so many signs of being abusive towards her (and normalising this kind of behaviour can be very dangerous to the people who watch it. It’s a very toxic representation of romance) that I'm really considering dropping it, just like I did with the manga. There are many times when you're supposed to feel sorry for Si but I really just couldn't because he didn't deserve to be pitied. Actually, all 4 boys used Shan Cai for their own means, and she was the only character who I actually felt sorry for.
However, the acting is fantastic on all accounts. All actors portrayed their characters well, especially the male and female leads. There was also a great variety of music, so it wasn't just the same 2 songs playing on repeat like so many other dramas have. I would never rewatch it though, because of the reasons above.
