[ As Charlie likes to say, you're only as old as you feel. Maybe Nanami has an old soul (understandable, considering), but Charlie is quite young at heart. They balance well, and it'll probably be easy to forget that Charlie is indeed an old man.

Though, for a second it feels like his old man heart is going to give out with how tender Nanami is being. A bit of color rises to Charlie's cheeks, surprised and delighted by such a sincere gesture of affection. ]

Only complaint I have so far is that you seem too good to be true. If I find out I'm dreaming, I'm gonna be pretty upset.
