1st of december is coming and the balkan countries decide to throw a surprise party for romania just like how they threw a surprise party for bulgaria (they kinda settled things out with him after the 3rd of march surprise party fiasco). so basically they greeted romania beforehand as to not make the same mistake like they did with bulgaria (but they didn't tell romania about the party). nevertheless they're ready for him to come into the room so they turn off the lights...
rustling of clothes and a zipper being unzipped are heard, coming from one person.
bulgaria: 'lmao romania's gonna be so surprised when he comes in and sees us all naked! :DDDDD '
serbia: 'OMG BULGARIA PUT UR CLOTHES BACK ON IT'S NOT THAT TYPE OF PARTY'
bulgaria: 'oh... don't turn on the lights'
AND RIGHT THEN ROMANIA ENTERED THE ROOM
also if bulgaria was drunk, he wouldn't care if they turned the lights on
