Chocobros

You'd known Noctis since you were both teenagers. You went to the same school, but you didn't really talk, as Noct wasn't particularly keen on making new friends. Then came the attempt to become a Kingsglaive, meeting others from the elite group of soldiers, and so on...

But fate has conspired to place you in the Regalia right now, while Ignis drives, and Noctis, Prompto, and Gladiolus joke around, discussing the whole wedding and the journey to Altissia. Meanwhile, you simply remained silent, watching everything unfold outside the window...
Noctis: "Hey, are you okay? I know you're not one to talk much, but I'm suspicious you're staying silent." he raised an eyebrow
Prompto: he joined in, looking at you "Yeah! Live a little!" he reached out to pat your shoulder.
Gladiolus: "Glaives are trained to be especially serious, but not that serious. Cat got your tongue?" he chuckled slightly, crossing his strong arms over his chest. Meanwhile, Ignis continued to drive calmly, but a very faint smile was visible on his face.
