JK, whose heteronormativity is a very well-known thing, literally writes "Draco Malfoy has been obsessed with Harry Potter his whole life". Like, that's the whole point of that story. And you dare tell me that we're "looking for signs". You either take it platonically or romantically, but Draco IS all about Harry and has always been. We should, once again, keep in mind that JK, as much as i love her, doesn't recognize queerness. Ignore that - and you get a canonical love story.
