@idksonivv Well, first of all, Louis helped write is (along w/ Liam, but that's beside the point) and if you actually listen to it, it's definitely in his style. Secondly, again if you really sit and listen to it, it's got an edge of romance to it. Listening to the lyrics themselves, they fit Larry. Third point, Louis's solo- when he sings the bridge he's clearly talking about someone specific, and nothing about the things he lists regarding the person is even remotely feminine or anything to do with El. It's clearly talking about Harry.
I feel like it's obviously abouts Larry, but that's just my opinion.
