I'm wondering whether the production team deliberately wanted to court comparison to Spring Day, with the train concept and the single tree animation. They had to know people will make connections.
I wondered the same thing, Aristophenes...
As for the song, *meh*. It’s a standard backgroundy nothing song for me. Plus, it’s my personal thing that I really don’t enjoy those airy fairy breathy cutesy soprano voices, and she *reeeeally* leans into that with this song. I know some people will enjoy that and say it fits the concept but it just turns me off straight away.
