Hey there hello.
Very interesting story, also I found a bug.
Image 'glowing_tree' not found.
[Spoilers?]
Sonata and Sonatina is especially weird for me because 'inha' is used in my language to represent something smaller/cuter. Because of this I thought Sonatina was Sonata's daughter lmao
The Aria ending is so bittersweet, on one hand she finally went on a date, on the other she forgot Legato. Personally, my favorite ending was the one where she talks to the old lady.
