That was fun, sometimes funny and really cute in the end. Art style isn't beautiful or detailed, but looks aesthetic and animation is really smooth and nice. It feels like it has some kind of message behind it, it can be intepretated like a story of a depressed person that was bullied and had no self-confidence. Your past experiences, or past version of you, is trying to convince you to revenge and hate - but it's not a real solution to the problem (that's how all the cliche villains are created, lol). You can't escape or get rid of the past, but you can create a better future :)
I watched all the book series and this video feels special - it's closing the whole series, but at the same time it works really well on it's own as a single story. Really good job!
