Such a bittersweet story, almost nostalgic for me. I love it starts out quite silly but ends up with such a level of sincerity, I'm quite taken by surprise, the conversation and scene flow quite naturally as well. The soundtracks were also very well composed and used well, maybe a bit sfx here and could really liven up the scenes.
I do wish there are more interactions somehow aside from the early parts, but it being quite linear works in its favour too.
