They play both in the World of Idols, with a focus on their Agency and Managers.

Both have a Love Triangle where the two ML are Idols.

Both have a Group that starts from the bottom.

Both have Character that is talented in composing Music.

It's not similar with The Great Seducer but Joy is in this drama too! So if you liked her you should watch it too!

Both dramas ais about a music producers who meets a girl with a beautiful voice and their journey into making it in the music industry.

Both dramas are about the main character's passion for music. Monstar seems to have a slight dark side to the plot that later resolves itself.

Pontifex Rembrary, a character known for his divine powers, gets transported to a new world while fighting a devil. He possesses the body of Woo Yeon Woo, a member of an unpopular idol group, and helps turn the group's fortunes around after a disastrous live performance. With his charisma and divine powers, he becomes popular among fans but faces challenges from his past, contending with strange religious groups and the devil.

Page turner is a mini drama that also tells the characters' passion for music, only classics. He tells about Yoo Seul is a student of an art high school. She is a talented pianist and who won various contests, but she is driven by her mother. Yoo Seul's mother wanted to become a pianist when she was younger. One day, Yoo Seul has an accident.

Both talks about the live of people who wants to debut in kpop world

Similarities: The fluffy romance and and adult is dating a high schooler in both...
Though the other things are quite difficult, because of that while I was watching HSKoS, I was reminded of TLaHL.

- The central point of both dramas is music
- The main characters in both are trying to become idols
- The Liar and his Lover focuses more on romance
- Dream High has more character development
- Dream High is more funnier - so if you like comedy...!
- Both leading actresses are idols in real life! (Not that that has to do with anything)

- Similar plot with MJ and Crude Play
- Main lead is a song writer
- I like the romance in both but TLHL has more sweet romance scenes

A love story about a depressed genius music composer Kang Han Gyeol who meets the high school student Yoon So Rim when he’s living under a hidden identity. With her courageous honesty and beautiful singing, So Rim draws Han Gyeol back to her again and again. They meet love obstacles along the way as So Rim finds out that Han Gyeol was actually Crude Play's producer K.

Both feature a struggling musician who falls in love with a younger girl through music. The Liar and his Lover (kdrama) depicts the forbidden relationship between a famous musician and an aspiring singer high schooler, but it has a much lighter tone than the original jmovie. Fight Song is more about two people who’ve been depressed finding each other, discovering new beginnings and falling in love for the first time.

Youth/Idol music dramas, OSTs are amazing and main leads are cute in both drama.

Both are Korean Musical romance dramas based on famous manga..............................................................................
