I'll start by what really didn't work for me : like almost every one, the 2nd lead couple.
Non seulement they had way too much screen time but en plus the setup of that deception is really so deep that there should've been no coming back (to be honest I skipped their scenes so I don't really know how he got her to forgive him)

Next, the poachers story doesn't feel organic and is just a way of adding useless scenes and episodes (with all due respect to the wonderful butterfly -worthy scenes of our leads there)

Now the main couple. To be honest, I was expecting something healthier there. The premises work ok for me : She is is funny and the way she's acting OTT is cute. And her bestie is all of us, TV Drama fan almost eating our pop corn on the front seat while a real life drama is unfolding before our eyes. I particularly love when TianTian tells Lv Jian that, as every 2nd ml before him, he's too late :D
Anyway, with the promising start and now being used to really healthy love settings (Forever Love, You are my Glory, Fly with you, Her Private Life...) I was hoping that the story wouldn't drag the "when will they..." For so long.
And ep. 28-30 (where I am right now) there are those useless lies she spouts for no reason. Not fan.

On the up side, I really dig every scene they share. I had vaguely met BinBin in Love O2O and even there is explosive... Sex appeal (??) was not lost for me.
And it was my 1st encounter with Yu Shu Xin. And I really love some expressions she makes with her face. So now Love between Fairy and the Devil got on my list, to see more of her.

I'm sorry my review is a little all over the place, I couldn't seem to organize my mind...
The next one will be more structured.
