Hungary's experience

Hungary: We've been best friends for decades. I love you. I want to constantly have you with me in my life. Will you marry me:
Poland: YES!!! FUCKING FINALLY!

Poland and Hungary kiss passionately. They decide to wait for the meeting of the Council of Europe to tell the others about their engagement. They do decide to tell Czechia and Slovakia however. The 4 go out for a drink.

Hungary: So we have a big announcement...
Poland: WE GOT ENGAGED!!!
Slovakia (to Hungary): Congrats bro!
Czechia: OMG!!! (starts jumping up and down in her chair from excitement)
Slovakia: So when's the wedding?
Poland: We haven't decided yet. Can we ask you 2 a favour? Please don't tell anybody about this. We want to announce it at the Council of Europe meeting.
Czechia: Sure!
Slovakia: Of course.
Hungary: Thanks.

The 4 stay together for a couple of more drinks before leaving. Poland crashed at Hungary's place.
Few days later the Višegrad countries drove to the meeting. It was a pretty comfy drive without any arguements between the 4. As they arrive they park, wait outside for a while before the meeting started. The recess happens. Poland and Hungary enter the big hall and sit next to eachother.

Poland (whispering to Hungary): I can't wait to tell them! I'M SO EXCITED!!!!!
Hungary: Shhhh, keep quiet, they'll hear you.
Poland: BUT I'M SO EXCITED SHSJHWJWHWEJHEHWUWJA

Slovakia and Czechia turn around knowing what the fuss is about. They smile at eachother and turn back to face the hall centre where France is currently speaking.
Romania asks to use the restroom.

Hungary: Jesus Christ, he can't hold it for 30 fucking minutes. Imagine if we had drove with him.
Slovakia: That would've been a nightmare.

Recess.

Poland: I'm gonna go use the restroom.
Hungary: Okay, I'm gonna catch up with you.

Poland leaves the hall. Hungary stays seated for a minute before getting up to go use the restroom. He stumbles upon Romania and Poland talking with Armenia. Both Poland and Romania look nervous and Hungary notices it. Bulgaria seems fine.

Poland: Hey sweetie! I was just talking to Romania.
Hungary: Oh yea? What about?
Romania: Oh, well Lithu-
Hungary: I wasn't asking you.
Romania: So?
Poland: Hungary please stop.
Hungary: So you're taking his side now? He stole my Transylvania!!!
Bulgaria: Hungary...
Poland: That was a long time ago...
Hungary: I DON'T FUCKING CARE, I DON'T WANT YOU HANGING OUT WITH HIM!
Poland: WELL MAYBE I DON'T WANT YOU TO TELL ME WHAT I SHOULD AND SHOULDN'T DO.

Hungary gets mad and leaves the building. He wonders if them being more than best friends is making him feel jealous. He fails to return to the meeting. With Hungary missing, Poland doesn't tell anybody about their engagement.
