Well sometimes rudeness is part of plot/story at least early on, which evolves into a love/hate relationship.
Here are a few that come to mind when it's obvious the male character is pretty rude:
Most rude:
- Boys Over Flowers
- Black
- Secret Garden
- The Last Empress (not like the others though, won't post any spoilers)
To a lesser extent, but still somewhat rude how male leads treat the female lead, or at least a rude indifference:
- Cheese in trap
- Goong
- Her Private Life
- The Master's Sun
- My Girlfriend is a Gumiho
- Something about 1 percent
- You're beautiful
- Cinderella and the four knights
- Playful kiss
