Maybe the criticisms come from that side, they didn't understand the plot or they don't like complicated plots.
I haven't watched this movie, but I'm glad that you didn't let the negative reviews guide you too much and you were encouraged to watch it and find out that you liked it.
The animation looks good and even though I already got the spoiler haha it doesn't matter, I knew I would get it and the plot reads interesting 👌
The same is my friend, although it is a slightly complicated story, it is still a beautiful story that at the end of everything is always about love. Thank you for your comment.
