1D fans are pretty convinced that the song is about Harry Styles, his former One Direction band mate.
Since it's kind of romantic, fans realise that the lyrics are about a love lost, so it can't be about his current girlfriend Gigi Hadid.
There are lyrics like, "I've been f*cked and I want ya, I can't even text ya/ 'Cause my fingers ain't broken, but my heart is," fans think he's considering texting Harry.
Fans even think that Harry is secretly promoting Zayn's song.
Interesting concept. What do you guys think?
