Ping Pong The Animation, Shigatsu wa Kimi no Uso Recommendations
Bespectacled protagonist with an immense talent struggles to actually be able to use it. Two main characters must brave the gulf that has started in between them. Both protagonists are sympathetic and wonderfully designed.
Both hit you hard in the feels and use a specific medium (Ping pong - Music) to advance the plot and develop the characters, without it overpowering the story.
