Both dramas are about music industry. In both you'll be able to see a group of 'kids' trying their best to debut, true friendships and loyality, love between an idol and a non-idol, achieving dreams, dating issues and the most important: a music company lying fans in order to cover their idols and keep their company up.

Both these shows are good for anyone that likes Romance and Comedy and want to see what happens after the two leads become a couple. Both as have actor Kim Hyun Joong.

Lady Joker is a loose sequel of Marks no Yama. Both are short, dense, thrilling drama with great acting and brilliant writing

Both heroes are charismatic, and both of them are Robin Hood type. a hero fighting against the selfish and corrupt government to save the ordinary peasants.

Great action, anguish, and greatness. Both involve fighting off Japanese influence as well

They are both body swapping rom-coms. But in PPO the female lead switches bodies with the male lead's niece.

Both leading actors and actresses give off the same vibe. Similar timid, innocent girl and arrogant, workaholic, obsessive heir. Even the development of the story and the relationship between the main actors and actresses are very similar.

Both are love stories about a top star and a regular girl. Also in both stories the male lead uses another girl to try to make his childhood love upset. But in Jai Rao the female lead is his childhood love.

The road home is a better drama to me but they do have a similar feel maybe because they are family dramas lol

They were filmed 1 year apart, they both have Park Hae Jin and LOT's of family issues lol - idk, I just think they have a similar feel

Both has Wallace Huo, and Tiffany Tang as one of the lead couple. It's a funny rom-com, with a bit of action, and shows the couple in a less serious way.

In both series we ask ourselves if the main character is either good or bad. As the action advances we discover his reasons for being like that.

Elder woman x younger man.
Two people living together and getting to know each other.
