Both focuses on life in a village, seen from the eyes of an adolescent girl.
Music forms an important part of both movies. They have the same laid-back feel, and both are directed by Yamashita Nobuhiro.
Both are comedy dramas that don't take themselves too seriously (and neither should the viewers!), but not without some genuinely touching moments.
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.
Both involves the hunt for hidden treasure of some sort (money from a bank heist and a stash of gold)
Both are slow starters with well-crafted stories and secret gold stash in the crux of their mysteries.
The main character(s) of both shows fails to achieve their longtime dream, and had trouble adjusting to their new job at first, but gradually finds pride and enjoyment in their work.
Both are hilarious, with zany characters and over-the-top acting. Somewhat more oddball than typical Korean comedy dramas.
