It sounds like an experimental song that you might find somewhere unknown in 2008 while you were looking for something totally different, and somehow it was hypnotizing.
The instrumental is good, you can use it for other songs and mix it up, I think the only thing you should improve is the parts when Rin's voice gets too high, but other than that, the song is good
How about you produce a song ❤❤ It’s not easy making a song like.. Lmfao atleast give constructive criticism to this beginner producer instead of being harsh on them for mo reason
