Romania/Bulgaria

Romania/Bulgaria is a common pairing involving the characters Romania and Bulgaria. It is also known as RoBul, RomBul, or BulRom. Some fans use Vampire Rose, which comes from Romania's constant acting as a vampire and Bulgaria's national flower.

Relationship
Bulgaria and Romania are best friends, with almost all of their appearances being accompanied by the other.

Romania and Bulgaria bonded and became good friends during the time they were both being controlled by Russia. Romania immediately takes to Bulgaria's suggestion that they should sing (about Russia) to pass the time whilst they work, and later talked in an animated fashion to Bulgaria about his history and mythos. Initially, Bulgaria thought Romania was a weird guy and was put off by his unsettling stories. However, upon speaking to him more, Bulgaria realized that Romania was actually more normal than he initially thought.

They later joined the European Union at around the same time. In the Halloween 2011 event, they went together as an angel and a demon, and their wings got tangled together. They also hang out together during that year's Christmas event. They attend the Halloween 2013 event together as well, with Romania disapproving Bulgaria's costume, an imported Attack on Titan military jacket (a nod to how much Bulgaria resembles its main character, Eren Jaeger), and attempts to force him to change clothes. Later, Bulgaria attempts to comfort Romania by offering him his jacket, after Moldova rejects him for Russia out of fear (of Russia). He states that Romania should not worry about being a failure as a brother, as he and Bulgaria are the top two disappointments in the EU, which upsets him further.

In the present day, the two remain very close friends. World Stars chapters 399 and 400 show them exiting a world meeting and deciding to go get drinks together, wanting to forget about getting told off by Germany. When they are approached by Moldova, who is crowdfunding to get more money, Romania becomes upset because Moldova did not want to ask him for help, knowing Romania couldn't afford it. Romania started to cry because he made his little brother worry about him and vows to become rich and strong so that he can be more dependable. Bulgaria comforted him, saying here's no point crying over things that will be impossible to achieve They then decide to go get drunk to forget all of their problems and do better the next day,

In Chapter 403, at another world meeting, Germany turns around and shushes them for talking over the presenter. When the nations get told that among the sibling nations, younger siblings are having more economic growth than their older siblings, Romania begins to freak out. In the ensuing commotion, Bulgaria, while comforting Romania, yells at the (presumably human) presenter that he knows nothing about nations and cannot decide things like that. When Bulgaria is approached by France and Luxembourg for an inspection and "life guidance" at Germany's insistence, he becomes stressed and upset because of how badly he is doing. He decides to read a number of EU reports to put his mind at ease, knowing that Romania has a similar track record to him. Here, he refers to them as "connected by our souls", or soulmates. However, he discovers that discovers that Romania is doing much better than him in a lot of rankings now, and begins to fear that Romania wouldn't want to be around him anymore. He rushes off to Romania's house to talk to him. He shows Romania the reports and expresses his envy that both Romania and Moldova are improving so quickly, and sadly suggests that Romania may want to become friends with another group instead of being lumped together with him anymore. This conversation happens with Bulgaria standing outside and Romania leaning out his window.

When Bulgaria turns to leave, Romania leans further out the window and grabs his face, and the entire following conversation takes place with Romania tenderly holding Bulgaria's face in his hands. Romania tells Bulgaria that while yes, he has been improving in some areas, he still has a lot to work on. Romania also assures Bulgaria that they are still similar in different ways, and they are both still far behind other EU members. Bulgaria wipes his tears and realizes that they can still stick together because of these similarities. They also bond over both liking Windows7. Once they are done talking, Bulgaria says they should go out for drinks, but Romania suggests they stay at his house and they will also bake plăcintă, a Romanian pastry dish.

Fan Speculations
It is a common trope for this pairing for Romania to be a vampire while Bulgaria is a human character that will soon come into contact with him.
