Many people thought that they are rivals.

But no. They are close as fuck.

Everyone who has 2ps are very close to each other, even if they are different.

Matt and Matthew both love hockey, and would do a 1 vs. 1 in their free time. (And sometimes won as a draw.)-

Even he is girly as shit, Flavio and Lovino are really good cooks and would cook for their brothers.

Kiku and Kuro work together really well. Kuro is a expert fighter like Kiku. They also matchmake other people together and would watch anime together.

Lutz and Ludwig would be really unstoppable once war starts. They are brilliant strategists for war, as well as good fighters.

Francis and François sometimes discuss about family problems and would smoke together.

Oliver and Arthur are both experts and dark and light magic. Experts. Sometimes, Oliver would teach Arthur cook so everyone would enjoy his cooking.

Like the Germanys, Ivan and Viktor are also brilliant fighters and strategists. Ivan would swap clothes with Viktor so Belarus won't easily tell which is which.

Yao and Yang are martial arts masters. They would train together and sometimes, eat tasty Chinese treats together.

Alfred and Alex would converse about the latest movies and games. Other times they would play FNAF or watch The Game Theorists for mindblown shit.

If either the 2p or 1p dies, they would fall into depression easily. Why? Because they love each other as brothers.

This is the main reason why Feli can't kill Luci.
It's because they are close, even though they are different.

Ok, I should make a funny one. XD
