A/N: I don't own Hetalia.

I dedicate this fic – with lots of love and appreciation – for my marvellous little sister, Nitzka. I hope you'd enjoy this, dear! ;D

Original request: "there is a TV show, where two families trade wives for two weeks, and the families each learn something about themselves and how they can become a better family unit. Typically the show takes families from extremes, like extreme conservative and extreme liberal, for the swap and the families find some sort of balance.

Basically, Anon wants to see two couples doing this, and how the families adjust to the changes involved. Anon's favorite couple is Sweden/Finland, so if they're included that would be extra-nice."

Wife Swap

PROLOGUE - FINLAND'S POV

"It doesn't make any sense. Why would anyone like to do such a thing?"

Finland looked at Denmark, who sat next to the kitchen table and rocked over his chair, even after the tenth time Finland warned him he might fall off. The latter grinned, "because it's on TV!"

"I don't know. I can't find any logic behind it," Finland sighed and turned his back to Denmark, continuing to cut the vegetables for dinner.

"It's simple," Denmark turned his torso to the younger's direction, putting an arm on table to support himself, "it's a programme that contacts couples from all over the world, and swaps them in order to let them discover new cultures or something like that." He paused for a moment, before he added in a sly grin, "c'mon, Finny. I thought you wanted to travel around the world."

"I do, but this sounds bizarre. I don't even know why I even effort to speak with you about this."

"Why won't you give it a shot?" Denmark didn't give up. "I'm sure you'll enjoy this. You are the nicest guy on earth, they're gonna love you!"

Finland sighs, "I don't know." He paused. "What Sweden would say about this?"

"Oh!" Denmark jumped in his place, and fall off, emitting a painful groan as his body touched the floor. Finland hurried to him and helped him to get up. "Are you okay?"

"Yeah."

"I warned you, you shouldn't rock on chair like that," he noted.

"Yeah, whatever," Denmark returned to his chair, before he smirked. "I actually asked Sweden earlier. He said," Denmark's smile got even wider, "that's not a bad idea."

"Really?" Finland raised his eyebrow in suspect.

"Yes. He's about to return soon, isn't he? You can ask him yourself."

Finland sighed, ignoring him for the rest of the time before the front door opened and shut blown a moment after by a fierce wind carried from the storm outside. Soon, Sweden's low voice filled the space, "I'm h'me."

"S… Su-san!" Finland called, hurrying to greet his 'husband' for the moment he entered the room; the Swedish put his palm on Finland's shoulder and was about to bend to kiss him, when he eyed Denmark, who grinned from ear to ear. He straightened and turned his face to him, his palm is still on Finland.

They all stayed like this for a few more minutes, until Finland cut the silence. "Su-san?" he managed to mumble, tensed. Sweden immediately turned to him, lowering his head a bit.

"Y's?"

"D-Denmark-san t-t-told me a-about of s-some programme," Finland paused, taking a deep breath to calm himself before he continued, "Wife Swap, or something like that." He paused for a few more moments.

"Y's. H' t'ld me." As Finland couldn't utter a word, he asked, "Wh't 'bout 't?"

Finland seemed a bit troubled, "y-you don't really think we should apply this… do you?" his face were pleading; Sweden noticed, and blushed.

"Mm…" he mumbled, clearing his throat, "'ct'ally…" he cleared his throat once more, "'t s'unds l'ke a n'ce 'dea…"

"Haha!" Denmark exclaimed, rocking his chair dangerously, "Told ye' it's a good idea, Finny!"

Finland blushed; he just couldn't believe his ears. He looked at Sweden questioningly, increasing the latter's blush. Sweden emitted a silent unconfident gasp, before he gathered himself, put his two palms on Finland's shoulders and bent a little. "Y've 'lways l'v'd trav'llin'…" he mumbled to his ear.

He nodded, taking himself a few safety seconds for any possible regret before he said, "Alright. I agree to do it."

"Told ye'!"
