You were aware that Prompto loved photography, and he didn't even tried to hide it. However, you also noticed that he liked taking photos of you, specifically. And, if he was trying to hide that, too, he wasn't doing a good job at it.

One day, while Noctis, Ignis and Gladiolus were out doing something (probably shopping for Ignis' recipes), he grabbed you by the wrist, and dragged you in a spot that he had found some days prior, one that he deemed pretty.

While he loved taking pictures of everything—and everyone—he seemed much more enthusiastic now. He released your wrist, before taking some step backs, and taking out his camera.

"Come on, pose." He encouraged, readying his camera. In fact, he had already started to take pictures, even if you weren't doing any pose. You were attractive, even when you were standing idly, doing nothing.
