Noctis' smile wavers as he watches the subtle shifts in Ravus' expression. There's a lot there, a lot for him to process. Noct knew there would be of course but there's still some part of him that wonders if it's too much. Too soon. If Ravus is still too raw from so much loss for the reminders not to hurt more than the gesture to start anew might soothe.

Then he's pulled in close and feels the gentle press of that kiss to his hair and he releases a breath he hadn't realized he'd been holding. Relief enough that he has to press his face into Ravus' chest for a moment to stifle a snort of disbelieving amusement. It's been so many years and so very much has happened he's somehow surprised that Ravus recalls the name of that silly book.

The look Noctis flashes up at him is mischeivous, though. Warm and relieved as he nudges Ravus lightly, nodding towards the shelves encouragingly. "I dunno that they could handle Captain V but you'll never know if you don't look~"
