Zayn questions himself on “Rainberry,” asking if his significant other, presumably his then-ex-girlfriend Gigi Hadid, is cheating.
Although Zayn hasn’t specified what the term “rainberry” means, it could refer to the Gatorade flavour or Gigi Hadid.
Zayn released “Rainberry” as a surprise on November 30, 2018. It serves as the first promotional single for "Icarus Falls", which was released exactly two weeks after the song. .
