O Mentiroso e Seu Amor (2017)

Lee Shin is a university student majoring in modern music. He is the vocalist of the band "The Stupid" and also plays the guitar. He is known for his good looks and his strong passion for music but is in reality a cold person who is uninterested in non-music related things and has no dreams nor plans for the future. Shin initially likes a dance professor at his university, but this all changes when he meets Lee Kyu Won. Lee Kyu Won is a bright and outgoing student who was born into a prestigious family and is majoring in traditional Korean instruments, especially the gayageum. Kyu Won's grandfather, Lee Dong Gun, is one of the top 3 traditional musicians of his age, and his biggest wish is to have his granddaughter trained to become a traditional music prodigy in 10 years' time. Trying to live up to her grandfather's expectations, Kyu Won immerses herself in training and becomes a university student who knows nothing besides traditional music. As Kyu Won's friends are fans of "The Stupid", she was forced to go to the band's concert with them. There, she saw Lee Shin performing live and is immediately captivated by him.

The Korean version is the remake of the Japanese movie. Therefore, they have the same storyline.

Not really, the plot is pretty much the same but the K-drama feels cheesy somehow.

At first, I watched the K-drama (in 2017) and I loved it. But as I watched the original Japanese movie (2013 version), I felt that original is always better. As much as I liked the leading man in the K-drama, the leading man in the J-movie is much more intense, charming and charismatic. The personality of the leading man in the K-drama did not quite convey that aura. Not sure, maybe because its a drama and they had to make it long somehow to make it interesting...

I just liked the J-movie more. But for sure, watch both. Why not.
