In order of relevance you should watch:

-Pride
-Buzzer Beat
-The greatest love
-Kill me heal me
-Tatta hitotsu no koi
-The moon that embraces the sun
-Fated to love you
-It's okay that's love
-Rooftop prince
-Marriage contract
-One more happy ending

I recommend I Hear Your Voice.

I hear Boku no Yabai Tsuma was also good and is on my PTW too.

And then I'd also try more episodes of Bridal Mask and Coffee Prince from your On-Hold list.

I've only seen 3 from your PTW list and out of those 3 the only one I can recommend is Liar Game.

I Hear Your Voice!!! -- This is sooo worth watching, believe me!
Uncontrollably Fond -- really good, if you love beautifully shot melodramas. 
W -- Two Worlds -- only the first 2 episodes are out, but this is SO good! Also the plot is very unique.
If you like calm, emotional dramas that concentrate on the family part a lot, I also recommend The Spring Day of My Life. :)
