One and only one drama? That's a good one... I guess I would have to go with Ten Miles of Peach Blossoms. I feel it covers everything one would possibly need in a drama: romance ✔︎ action ✔︎ comedy ✔︎ It has a bit of everything for everyone to enjoy. Yea, it's nearly 60 episodes and that in itself can be daunting but it's worth the watch. No lagging story-line, no crappy acting, and NO WOODEN KISSES!!! I rarely re-watch dramas as there are so many that I have yet to see but this one... yea, I can see myself watching this again in the future.
