It was a day of the meeting and because all of the nations brought their little chibi nations with them, they decided to have a break and go outside to let the little ones play. You were standing shyly behind Mama Ukraine holding a plushie kitty cat that you had made with the help of your mama.
"Go on hun, he'll love it." Your mama said. You stared ahead curioulsy at the brown haired chibi boy playing with a grey furred cat.
"But, but- but." You started but couldn't find an excuse.
"Go on." Ukraine said giving you a gentle shove on chibi Greece's direction.
You stumbled a bit but walked ahead nervously. Your cheeks  tinted with a slight blush as you neared the sleepy looking boy.
"Hello (name)." He said to you with a sleepy smile.
"H-hi." You said nervously holding the plushie kitty behind your back.
"What is it? Your face is red." He said bluntly.
"Oh, umm...here. I made this for you." You said closing your eyes holding the kitty plushie.
You peeked your eyees open and saw him smiling at you. He held his hands out to take the plushie from you. Once he had it, he looked it over and then looked at you.
"Thank you (name), its really cute like you!" he said which sent you into a blushing fit. He got up and gave you a hug.
"Here! I have a present for you too! Japan gave me them!" Greece said going away and then quickly came back, with cat ears. He placed them on your head, and then some on his own head.
"Now...we can both...be..cats." He said sleepily. You giggled and joined him in acting like cats.
He sleepily rubbed his head under your chin, meowing softly. You giggled and blushed and meowed softly back.
The two of you played around, pouncing softly on each other and playfully chasing each other. Then the two of you saw two cats that were rubbing softly and doing something that intrigued you.
"What are they doing?" You asked.
"Come on, they need privacy for mating." Greece said and dragged you away.
"What's mating?" You asked.
"It's like getting married." Greece said.
The two of you stayed silent as you headed back, Greece still held the kitty plushie in his arms, and you blushed realizing he was holding your hands.
When the two of you sat back down, he started to rub his face to yours.
"(name), thanks...for the kitty." He said and then kissed your cheek.
"Your welcome." You said, your blush coming back.
"hey...(name), when we're older nations...will you...be my mate?" He asked you curiously.
"Y-yes." You stuttered smiling like an idiot.
Greece gave you a sleepy smile and then kissed your cheek.

~Extended ending~
"Mama! Mama! Guess what!" You cheered as the two of you went home.
"What hun?" Mama Ukraine asked.
"When I get older, Greece and I are gonna mate!" You cheered.
"Wh-what?!" Your mama asked, and going into mama mode. When the two of you got home she went to the phone and called Turkey.
"Hello Ukraine what is it?" Turkey asked.
"What is it I hear about Greece wanting to mate with (name), when they are older?" Ukraine asked sternly. She could almost hear Turkey gulp, everyone knew not to get Ukraine into mother mode over (name). Not after the incident with France.
"He should have talked to me! (name), is a daughter to me! These people now a days are so forward. What happened to asking the parents first?!" ukraine said tears brimming her eyes.
"There, there. I'll talk to him." Turkey said hanging up.

~With Greece and Turkey~
"Greece! You got me in trouble with Ukraine! What the hell is it with you and mating with (name)?! And what the hell is that in your arms?! Is it another one of your stupid cats?!" Turkey yelled at Greece.
"It's a kitty that (name) made me, and I wanna mate with her when we're older stronger nations! And cats aren't stupid!!!" Greece yelled.
"What the hell am I going to do with you?" Turkey asked facepalming himself.
