I connected with this. It's an 8+ for me. The acting was solid, they really spoke with their eyes.

Jazz is juxtaposed with Classical music. Classical music has strict rules Jazz is free flowing. Classical music is a metaphor for current Korean society and Jazz is a metaphor for the LGBTQ community. The story deals with negative themes like violence against yourself and others and denial versus positives themes like self-acceptance and love. It's well worth watching.
