Haruta & Chika (2017)

Both female leads love instruments and are in the instrument club.
Both stories have a simple love life (without 2nd leand and so on)

The movie Haruta & Chika is about this high school music club that Chika tries to revive by asking students to join the club together with her old friend Haruta. The music club prepares to join a contest with other schools.

The drama Aogeba Toutoshi is similar, here we have a music professor that takes care of problem students and also tries to convince them to join the music club and aim to get first win in a contest with other schools.

This drama is a bit more serious and dramatic while the movie is cheerful and comedic. Both of these give the same vibes.

FL & ML love story influence by music both student & studying music together. I like movie/drama with music as the main theme with romance.
