America pov
  I was close to waking up after dreaming of winning another chess game against Mexico.

  As I returned to the normal world, however, I felt a strong warmth close to me, so pleasant and sweet, as if someone was hugging me.... no wait... WHAT?!.

  There was someone in my bed, now I could feel their arms around my hips. What if a maniac had kidnapped me?!.

  To defend myself and put whoever it was offside, I kicked the person next to me hard, so hard that they were thrown out of the bed.

  I opened my eyes and saw a panting Russia, lying on the ground and with one hand resting on his belly.  "RUSSIA FUCK".

  I bolted out of bed to get close to him.  I put a hand on his shoulder and stroked him gently to calm him down as my face turned red with embarrassment.

  "I'M SO SORRY, I DID'N'T THINK IT WAS YOU... I WAS SCARED.... sorry".

  When he returned to normal breathing, he turned to me with a dark face, he threw off my hand and pushed me to the ground.

  "HEY, WHAT?!".

  He turned to my protests.

"WHAT?!, YOU JUST KICKED ME STRAIGHT IN THE STOMACH, DOES IT LOOK NORMAL ?!".

I did not understand, perhaps for him to sneak into other people's beds is normal.

"I felt a person hugging me from behind and I don't think i just accepted this person into my bed, it's obvious that I kicked them no? What if he was a malicious kidnapper?".
  "And who on earth should have kidnapped you... a zombie?!".
  "How do you know this is impossible?!".
  "WHY WOULD A ZOMBIE HUG YOU?!".

  "WHY WOULD YOU HUG ME?!".

Silence fell in the room, we both did not know what to say or rather he did not know how to reply.  We were red in the face, even if he was more, I think also due to the fact that he was angry as well as embarrassed.

  "Whatever happened, just forget about it, let's go eat."  That said, he started to go into the kitchen.

  But I still wanted to know how he found himself in my bed, I wouldn't let him go so easily

  "But Russia I want to know why-".  I couldn't finish the sentence because Russia grabbed me by the collar and looked me straight in the eye. 
"America, i said forget about it".
And with that he dropped me to the ground.

I thought that zombies couldn't have sense of touch but i felt hurt and not a little.  I snorted and went into the kitchen where he had found some chocolate chip cookies.

Maybe I scared him.

I turned to look at him but his face looked more annoyed than angry.  I smiled to myself, it was funny see him whiteout his usual smirk.

I was angrier with myself, I never imagined I would fall asleep with him after that nightmare.

After taking a glass of water, America sat down next to me wanting a cookie but I had already finished them all.  His angry face was hilarious and I couldn't help but hold back the laughter.

  After a couple of minutes of silence America finally made up his mind to talk: "Aaaah, what a bitch you are, okay i'm sorry but the fault is mainly yours though".

  I looked at him and then lowered my head, receiving a maddening sound from America's mouth.

He git up and went into the living room, that was my moment.

I walked over to sidestep while he was narrating towards the window, I took him by the hips and made him spin, lifting him off the ground.  He started screaming while I laughed like crazy.

  I wanted to make fun of him like he always did with me and then this is revenge for having a kick in the stomach.

  I set it on the ground and swirled it so I could see him in the eye.  His frightened expression and his red face were too much not to laugh.

  "Look who's all red huh?~".  He came to himself after a few seconds and smiled mischievously. "If we're talking about you I can see it very well~".  I smiled and let him go, for these few minutes of fun, the anxiety and fear just vanished to be replaced with joy and I felt so relaxed.  Maybe we should spent more moments like that to stay sane and relaxed enough.

  "Since when did you start answering in this tone?". America asked out of the blue making my smile widen. "I learned by imitating a little countryhumans with fifty stars on the flag~".  He started laughing and I felt my heart melt for some reason.

  We went to sit on the sofa to discuss, we need a plan. "Hey, you said we have a few days left before their bodies rot, right?"

  I nodded, continuing to look at Russia.
  "So... what do we do now".  I looked down, how could I know what to do in such a situation. "We could look for other survivors but...".  The only idea that came to my mind was this, the only one I thought about every day, pathetic.

  "I'm sorry... but I don't know what to do...

  If there was another country here in my place... he would have known how to save them all. "

  It was at that moment that I finally asked myself why, why I was still alive of all, I don't deserve to be.

  Russia watched me as I sobbed louder and louder.

  He put a hand on my shoulder and brought me back to his chest, like he had done the night before, stroking my back.

  I swallowed my saliva and sighed. "Why it is me who among all is still alive, I should have died, there were countries could  have saved everyone without wasting time if they were alive... it's not fair."

  Russia said nothing, letting me calm down, continuing on his up and down with his hand.

  "There is no why America, you are alive because this is how it had to go, we do not know what would have happened if there would have been someone else in your place, you just have to think that you are here and that you cannot waste time mulling over one thing we cannot know... destiny always has its own plan and everything we have to do is follow it, whether we like it or not... ".

  My breath stopped, I never imagined that Russia could have said a sentence like this... so... I don't even know how to describe it, philosophical I think?  More or less?

  "These were some of the last words my father said, when I realized he was going to die I didn't want to accept him and so he gave me all that speech, I think...  he knew that on my path I will lose many people. I will have to face many injustices... but that I cannot waste time imagining these words where something different happens... it is a waste of time to dwell on the ifs and buts... sometimes I think back to these words when something happens to me, especially not pleasant experiences , I stop wasting time and focus on the path I have in front of me facing everything... "

  I continued to hear him, I did not understand the reasoning well but Russia seemed to be sure of what he was talking about.

  "Of course... it is impossible not to imagine different situations... and I too have recently started thinking about the recently... but from now on I will not do it again...".

  Russia put his hand on my cheek and lifted it, bringing me to his eye level.
  My heart was really beating unnaturally, too fast and I could feel it throbbing in my throat.

  He looked me in the eye before he spoke again.

  "Hearing what you said earlier, you reminded me of these words... you reminded me of my father... thank you."

  I blushed slightly, still not able to understand what he was trying to tell me.

  Russia brought me back to his chest and continued to caress me behind the back of my neck.

  He was right about one thing though, I had to stop procrastinating, it was time to do something.

  "I didn't quite understand what you meant and I don't even want you to explain it back to me... I just want to tell you that I will try to save them... even if a cure would be needed here... like a medicine and I really don't think I can create one in the state I am in... even if I'm really a genius in chemistry and medicine... not to brag. "

  Russia sighed and stopped stroking me.

  "I'm good too and I can help you, look, you're not the only one here who can save them."

  I chuckled, he was right, I was no longer alone, I no longer had to look for other survivors, I had him now, finally someone.

  "So will you help me save my family?~"
  "All the others too!" "Yes the others too, however will you help me~".
  "..."

  "Yes, we will save them all."
