This fluff is fem!Germany/Prussia…wait, why did I put fem!Germany first…?...never mind…
"Oi, West!" Prussia ran down the halls, carrying a computer and Gilbird bouncing up and down on his head.
His sister glared irritatedly at him. "Stop calling me that."
He slid to a halt in front of her, mouth agape. "I've called you West for almost a century, and you want me to stop now? Why?"
She blushed and turned away. "It's nothing."
He grinned. "Come on, little sis, tell me!" He prodded her shoulder, following her and repeating the same phrase insistently.
"Fine!" She whirled around. "I don't like it when you call me West because West is opposite of East and the opposite cardinal directions are farther apart from each other and I don't like that!" She gasped for air, having said all that in one breath, blushing heavily and pushing him away.
He stood, stunned for a second, before cracking his trademark smirk and saying, "Aw, I love you too, Louise." He pulled her into a tight hug, ignoring her squirming and kicking, not realizing when she stopped struggling.
"Lou-" She interrupted him by stealing a quick kiss.
"Kesesese, I know you can't deny yourself~" He crowed happily, spinning her around.
"Just shut up, Gilbert." But she smiled in spite of herself.
Aw you know you love it, Germany!~
