Persevere, Goo Hae Ra (2015)

Both focus on artists that are trying to pursue a successful career in music. In Persevere, Goo Hae Ra, there's one idol group too.

Both Entertainer and Perseverence, Goo Hae Ra are about the creation of a new music band.

It's not similar to Wind-Bell but Jinyoung is also in this drama! If you liked him you should watch this too :)

Both dramas are music and friendship. Young people trying their best to find their place in this world. Innocent & sweet.

Both dramas have a music theme. You are beautiful is more about being in a band whilst Perseverance, Goo Hae Ra is more about life in general and friendship.

Both dramas deal with similar issues, about finding who you really are and what you want to do with life. Both have music as the main theme.

Over the Rainbow is also about young people trying to survive in the music industry. It's a bit darker and more serious than Goo Hae Ra.

Both dramas deal with music, friendship, and competition. Both have a lot of kpop references.

Both dramas follow a group of youths in their musical pursuits. In heartstrings there is a rivalry between the ML if a band and the FL who is traditional musician. Through the course of the drama they work through their differences and learn how to make a performance inclusive to their respective genres. In PGHR, a group of childhood friends have a rift between them due to a misunderstanding during a talent competition. Although they end up separate in their musical endeavours, the truth begins to unravel as the drama goes on. Both dramas also star idols in their cast (Henry Lau, CNBlue etc.)
