This is a lovely story! Very sweet and genuine with enough little details thrown in that there's a good sense of the characters' personalities, daily life and bits of worldbuilding. I love the cinematography - it's clear a lot of love and care was put into animating everything and adding neat little touches.
One small side note: I ended up downloading the game because the text was hard to read on the web version because the window is pretty small. Maybe check the viewport dimensions again to make sure you set those right
