Spoilers ahead!!
I can say that I wasn't disappointed in this drama because I never actually expected anything from it; I literally lost interest ever since Eun Gi had her brain damage, I truly believe that's the main wrong turn in this drama because I seriously wanted to see a well-written revenge plot for the three of them.
Then, the main characters were never appealing to me: starting with Ma Ru who left his sister to die in order to save his lover (Yes, that's a fact that I will never forgive) going to Eun Gi who was a b*tchy rich girl who treats her brother in a bad way and hates her father (unethical moments that I can never forgive too) .However, she fell head over heel for the prince charming and decides to give up everything for him ending with Jae Hee who wants to go up no matter what heads she has to step on.
Basically, I didn't hate the way characters started the drama but what bugs me the most that they never changed through the whole storyline?s development; they never learnt from their experiences and kept on doing the same mistakes over and over except that Ma Ru fell for Eun Gi and that the B*tchy character became an innocent cat without much expressions but at the end Abracadabra, everyone's character changed to become perfect. I only liked attorney Park and I still believe that he's too good for this drama an there were Choco and Jae Gil too. Let?s not forget that the melodramatic atmosphere was absurd.
The end was very rushed because the writers just wanted to end it happily in order to make fangirls jump off their seats and give the straight 10's that I saw all over the reviews (no offence) but let's admit it, it was a huge ridiculous fan-service. I did rather that Ma Ru died instead of rushing everything in 15 minutes. Oh, I still don't think that Eun Gi deserves to raise her brother.
Oh, Jae Hee killed a man then she participated in killing Eun Gi's father, she confessed that she was the reason of attorney's Park accident and she only gets seven years while Ma Ru gets six years for killing a man without intention?! South Korea's law system must be messed up.
At the end, the reasons I didn't drop the drama and gave it a 5 (mostly 4.5/10 so I may change it to 4 later) are:
1) Attorney Park, Choco and Jae Gil?s presence.
2) Joong Ki was good here not only as a pretty face but he's a good actor so I was surprised to see this side of him after Sungkyunkwan Scandal.
3) The steamy kisses.
So as a conclusion, shallow feelings rated this drama 4 or 5.
