What's the drama title?

Hello! I forgot the title of the movie that goes like this: The guy was a famous artist and the girl was a music student. In it, she played gayageum, or maybe another instrument. The guy heard the girl played it and he saw butterflies. So, he followed her and pretended to be from a far-flung area. He also enrolled in the same department as the girl and they became close. And the story went ahead.

Does anyone know what this movie is?
