This seems like one of those animations you’d see as a kid, you watch the video and don’t understand a lot until the part that’s very sad, understand that part the most, cry for week or two or even longer, forget what the video was, a few years pass, you find a familiar video, it’s the exact same one you watched dating years back when you were like, 4-10 , rewatch the video and then you either shed a tear and feel sad, or just feel comforted and feel great you managed to find this again despite having no intent in doing so.
This is a masterpiece.
