Korea/Belarus is a lesser-known hetero pairing from the anime Hetalia: Axis Powers, involving the two characters South Korea and Belarus. It is often referred to as KoreBel, taking the first 4 letters from Korea's name and the first 3 letters of Belarus's.
Although the two haven't appeared together in canon yet, many fans ship them based on both characters' desires to unite with their brothers, Russia and China. The pairing is also seen more as a love/hate relationship, due to the two often seeming to disagree about how they should handle things with their brothers. The two are often seen to be driven by their desire to break apart their brothers, and are sometimes shipped in conjoinment with Russia/China. As well, they are often seen as each other's second choices, often dating after mutual rejection by their brothers.
