Please recommend me a drama

I'm looking for a Korean drama that is not too long to watch and something similar to the feel of 'Save the Last Dance for Me' and 'Cloud Stairs' - something sweet and romantic with not a whole lot of a 2nd lead (I hate second leads - females for sure) something that I can watch with peace of mind with lots of sweet moments in it - been trying to find one and all I can find are dramas that are over 50-100 episodes or more - they sound interesting but I really just don't want to invest the time it will take to watch them right now.... so a drama with 16-30 something episodes only...anyone?
