I think the music video for this song could be better. You know, it's mostly slow animations that honestly don't fit well with the upbeat tempo of the song and some of the cutscenes feel too much static, but it is pretty well-drawn and kawaii and shit and I love the way Yukika was portrayed there. The song is one of my favourite from hers, I really like the triumphant vibe of the synths and Teramoto's vocals are as sweet as they can get, just like in her Korean material and unlike the Japanese version of "Insomnia" which almost sounds like another person sang theparts in her native language. I can't stop listening to the song by the way and I genuinely recommend to watch this just for the song.
