Summer Days with Coo
" Coo , were you born over 200 years ago? "
" 😦 "
" Samurai sword? "
" 😰 "

watching a lonely kid slowly open up thanks to an odd little kappa feels less like a fantasy and more like remembering what summers used to be: long days , small discoveries , quiet joys , and moments of hurt that feel enormous at that age.
what I love most is how soft everything is , the pacing , the colors , the way emotions are allowed to sit without being explained or exaggerated.
It’s not about spectacle or big lessons , but about connection , empathy , and learning to care for something fragile , even when you don’t fully understand it.
by the end , it left me with that bittersweet feeling only certain childhood films manage to capture , the sense that something important has passed , but it shaped you in ways you’ll carry forever.
