I would love to watch a drama where the male lead falls in love with the female lead right away, or at least very fast -- Of all the dramas I've watched, I can only recall very few like that, and they only fit very approximatively: Boss & MeSecret Garden, Protect The Boss, and City Hunter a bit as well, I guess. Anyhow, something in which the male lead doesn't spend half the drama in denial therefore resorting to mockery / arrogance / cruelty.... 
Can you think of one?
Thanks!!!
p.s: please avoid dramas I've already watched :/

I second Moon Sun.
All About My Romance
Witch's Romance
Ruler of Your Own World

These stories have what you're looking for: the male lead falls for the female lead quickly (at least within the first 3 episodes).
