Who Are You - School 2015
She Was Pretty
Sungkyunkwan Scandal
Who Are You - School 2015
Boys over Flowers (I didn't even like the male lead)
You're Beautiful (same here)
Jealousy Incarnate
The Master's Sun could go either way for me
possibly Sassy Go Go
Kill Me, Heal Me did a neat trick in which I couldn't decide which personality I'd rather see stay with the female lead. Cool idea and some serious second lead (?) syndrome conundrum 
Cheese in trap (Have to agree, In Ho was so much better... but he was made to be 'the good friend')
Goblin (Grim Reaper and Sunny had a better story and much more chemestry for me than the main couple... maybe they deserved a drama just about them)
yes Bride of Habaek, I tried to watch the drama because of NJH but I just got annoyed of him in later episodes, Hoo Ye is a better match for So Ah

Manhole - the second leading girl (?) Jin Sook is more likeable than Soo Jin 
Loveholic - hands down!
I Need Romance
Lovers - I liked both male leads but I LOVED the dynamics she has with the second lead
The Heirs (watching right now and liking more the second lead)

Starting this list I thought I'd have more... :)
