You and Prompto have been dating for a year. He honestly never really understood how he ended up with someone like you, he always thought you were way out of his league, and so he constantly felt insecure around you even though he would never show it.

he would always get jealous whenever you would talk to noctis or anyone else that he thought was more your type, but he would never say anything. he'd just sit there in silence and watch you interact with others, letting the guilt and jealousy eat his insides

but that didn't go unnoticed. Gladio always teased him about it, but he noticed prompto would give him glares or told him to stop and so he decided to tell you about it.

and so you decided to have a serious discussion to him about it. while your boyfriend and you were taking a stroll, holding hands, you decided to point it out

"do you..feel jealous when i talk to other men?"

"huh? what kind of joke is that!" prompto laughed it off and continued to walk, but this wasn't a joke
