[prompto sways his head from his to side, allowing his shoulders a bit of a dance, as lunafreya talks and explains that he doesn't need to stay the entire evening. she leads him towards the banquet table by the elbow (which makes him smile proudly, straightening his back to be the most proper gentleman deserving of luna's company). he's heard her say this before, and he actually has half a mind of returning home before the event is over, because it really isn't his thing, being amongst all these rich folk.]

[however, it's her admittance that it's been a rough night that gives him room to pause.]

[turning to face her, despite the banquet table before him, it's he who sends her a slightly bemused but slightly scolding look.]

How can you expect me to leave early after you say something like that?

[he's mostly just teasing, taking on the Adult Tone to counter how it's usually her telling him to take things more seriously and stop getting so much into trouble (she means the absolute best for him, prompto knows). despite how different their lives and upbringing are, he knows-- prompto knows that lunafreya tends to push herself to the limit often.]

I'll stay.

[nodding, as if to affirm this thought to himself, he pats lunafreya's hand on his elbow]

That way I'll keep you company and I'll have a better chance of taking leftovers home.

[smiling at her now, he waits for the smile that is sure to come; lunafreya is family to him even if they aren't related by blood, so prompto wouldn't dare ever leave her when she's not at her best--especially when she's always been there when he has been at his worst.]
