See, it's cute on the surface until you think of it with dialogue.
Spain: Oh Romano~.
Romano: What is it, Spain Bastard?
Spain: *comes up behind Romano, wrapping his arm around Romano's waist, while intwining their fingers as he hold's Romano's hand with his free hand* (like in the picture bit without the neck kisses)
Romano: What the Hell do you think you're doing?
Spain: Oh come on Romano, Please? I've been good and behaved all of our date up to now!
Romano: No. Just wait until we get home!
Spain: *begins kissing at Romano's neck, voice husky and seductive* I think we both know neither of us want to wait that long, Roma~. I saw the way you kept looking at me at dinner, the way you kept looking under the table cloth like you were debating going under it. I know how much you love doing things in public, Roma, how much it excites you~.
Romano: *mutters* Damn Tomato Bastard. *Drags Spain off to the nearest bathroom*
(I might low-key use what I wrote right here as a role play prompt.)
