Yehua and QQ, of course.

Then Moyuan and Siyan

Followed by Sixth and Ghost Princess

Unlike most EL fans, I didn't like DH-FJ pairing. Was so irritated with FJ crying most of the time. So stubborn.
( Fast forwarded their scenes, sorry)

I don't know why I just really, really liked DH and FJ.  Maybe it's because in the U.S. you don't typically see her character in shows and I know it is more common in some of the Chinese and Korean shows I have watched (haven't really found a J-drama that I like).  I thought the characters had great chemistry and because of their differences perhaps room for character growth later--as in he would be less stone cold and she would be a bit more elegant, like BQ.  I didn't really like the romance between ghost princess and 6th (who I have been calling 16th up until now so many names!) because it felt like they threw it in last minute just to give her somebody.  

I think part of the reason I like her is because she is shameless. This drama is chock full of women who are following the rules or at least pretending to follow the rules and she just goes after what she wants. (The scene where she teleports into his bed...priceless)

Also,  I know he chose celibacy but I really think that the reason why he won't be with her because he fears rejection (remember his personal trial ended so abruptly and he continues to have thoughts of her that are anything but innocent although I invite anyone to disagree I like disagreements).  If he knows that the rock says they can't be together, why would he suffer and experience that feeling again? Why would he be in such a nasty mood following his rejection of her?  Why would he take the time to even explain all of this to her when he has never cared enough to do so in the past?  And I am more than certain he would be upset if she married someone else.  Plus, all is fair in love and war and love follows no rules, otherwise I doubt half these people would choose such painful (and one-sided) loves. 
And I think it takes a lot of guts to continue to pursue somebody even if they turn you down (fortunately she doesn't turn into a creepy stalker seeking to stop him from being with anyone else...like Si Jin, for instance).  At the end of the day, the episodes I find myself liking the most are the ones inevitably with FJ-DH although I do really like BQ-YH.  Anyways, I think my level of like is expressed by the sheer fact that I am responding to this post still :D   

the way i see it, DH doesn't love FJ as man love woman.. he care for her just like a man care for his pet..
obviously he can't give her what she want in real world, but at least he can give it to her in the fake world..
which is the heavenly trial
and its not because of love, but he did it because he pity her..

the feeling he had while in heavenly trial doesn't count, because its a fake world to him..
he is not who he is, he is just normal guy without celibacy status..
he is playing the role of different man..

@Tongko, if only I could upvote you... 

Haven't read the pillowbook yet but on EL, FJ was as stubborn as Su Jin and Xuan Nu.  Those 3 did not understand the word "NO". 

The only difference was, FJ was a protagonist (of course 2nd lead), while the latter two were villains. 

Perhaps I'll change my mind after I read the Pillow Book. 

And she actually leaves (i.e. gives up her pursuit of DH) much earlier in the novel.  She expressly leaves (I don't want to give away a spoiler) because of a significant event in DH's life and her reasoning is clearly stated that even though she is shameless, even she has to know when to give up because she is afraid of turning into a hateful woman (like Xuan Nu or Su Jin).  So she leaves and sort of buries her feelings for him.  I think if you read pillow back you will laugh and cry (like I did at the ending OMG I can only say that thank goodness I actually read the epilogue).

i haven't read the pillow book yet too.. 
this drama isn't based on the pillow book, its based on the first book..
which i haven't read either..

my opinion is based from what i saw in the this drama..
beside, most drama adaptation dont fully adapt the novel 100%, they change it here and there..
