Both protagonists stopped playing piano due to an accident. The romance and drama that happens in both titles bear similarities, meaning there will be "feels".
These series have piano prodigies as their main characters, and are mostly told in the male lead's point of view. In Kimiuso, it's the guy who used to be a piano prodigy and has a problematic past, and the girl helps him to overcome his problem. In Sayonara, it's the opposite.
