Korean dramas with poor male lead

I want to watch a drama with poor male lead until he becomes rich or successful 

Ugly Alert!!! I'm not sure if you'll like because it has 133 episodes of 30 minutes each... But it's perfect because you see the guy since he was a child and acompany his achievements , he doesn't become rich, but he could e he kind becomes successful. Well the story is about a guy that goes to prison for muder , when actually his stepbrother was the murderer. A really sad story, but at the same time really happy and the romance is great!
