Features Wang Yibo and well-known Chinese Skateboarders as they talk about the history of the sport in their country as well as their own personal experiences of learning from past generations and international athletes in their sport.

China’s “Keep Running” was actually inspired by South Korea’s “Running Man”, and was bought by the producers of “Keep Running” in 2014 for copyright. I would say these two are quite similar, because many of the games and activities are the same.

Both are female-centred dramas focused on the competitive nature of the South Korean education system. GMC could also be classed as a melodrama and involves a murder mystery, like Sky Castle. GMC is more of a slow-burn but if you enjoyed the themes of Sky Castle and Penthouse, you will appreciate GMC.

Both dramas have undercover cops
Both dramas have undercover informant or agent who has a daughter little girl trying to protect
Both dramas have secret past of the main lead and suspicious alliance

Two dramas about undercover cops
two dramas have a cop with secret past

There is a particular atmosphere, very dark. There is a really good twist and an open ending. And the duality between the two leads is well used to buid the story.

Found few similarities in Never Say Goodbye and Day Breaker!

Symphony's Romance is a very nice and beautiful story about university students of a music major. It is very similar to Childhood Sweetheart Pianist.

Both have a female Korean celebrity (an actress) falling in love into an ordinary person and learning to love him the way he is (even if he isn't perfect or has a status).

Both have younger female protagonist and an older male protagonist.
They are very different, but might bring the best in themself by the long run.
