Veneziano can tell that this is going to be fun, although probably not for Germany considering how many other people are in the room and can hear him if they try.
Hopefully nobody's going to try, and it'd be difficult anyway, since Germany had stuck his face into the side of Veneziano's neck, wrapped his arms around his waist, and just… stayed there. Mumbling.
Veneziano pats his head rather absent-mindedly, enjoying how Germany leans into his hand and raises his voice a little. He's pretty sure he hears "liebling" somewhere in the mumbling, and grins to himself. Germany tilts his head just enough to look up at him, and he actually looks pretty adorable, all flushed and wide-eyed and smiling, and Veneziano pulls him up just enough to kiss him on the cheek.
Germany appears to take this as incentive to try to right himself for long enough to pull Veneziano into his lap, nuzzling into the side of his head, and settles again, still smiling. "Y're really cute," he says in a sort of vague, cheerful tone. "I like you."
Veneziano replies in kind, and Germany makes a happy, humming sort of sound and falls back into the mumbling.
That's definitely "liebling" that he's saying. And then "stay".
"Of course!" Veneziano smiles broadly.
Germany pulls back again, bumps noses with Veneziano, and ends up kissing him.
This is going to be fun, or will be if Romano leaves the room before he notices.
