You know, it really makes me cringe when people say that Noctis isn't interested in Luna through out the game and movie (same goes for her). Like, do they even know how Noctis is?. He is really shy about those things in general, and especially around his friends. Only after her death does he realise how much he actually loves her. Like sheesh, it's really sad to see what people come up with to justify their own ship. The ending says it all in my opinion. They maaried out of their own free will.
