The melody fits surprisingly well :D I was searching for a demo version of "Pink Hair" because I could've sworn I've heard a similar song before. I don't think it's "Sure Thing" but it does fit together somehow, nice find! :)
My headcanon: Wanting to break off from rock music, Taka wanted to go more of a pop route, so he released Blank Space (Taka's Version) as his lead single on his debut album, 1988.
