Cinderella by Cidergirl. Aka, the intro to Komi cant communicate season 1

Hikare Inochi is a close second

Idk why, something about the song, the story told in the lyrics, the upbeat hopeful tone and the story it’s attached to just resonates with me / i related to it. I memorised all the lyrics off by heart and it was the only song i ever bought from the itunes store to use as a ringtone and to listen to off wifi. Still my favourite now, and i hope it will stay that way.
