Yoo Na's Street (2014)

Both are low-key dramas featuring a main character who works as a pickpocket. Ruler of Your Own World is somewhat more melodramatic while Yoona's Street has a slice-of-life vibe to it.

The way Yoona's street is shot reminded me a lot of Miss Korea. Both dramas have great written characters and development throughout the entire show. I also believe that both of these shows are underrated gems that don't look all that interesting on paper but leaves you satisfied all the way through to its conclusion.
