(THIS IS JUST MY HEADCANON!) These 2 are still trying to get the hang of living with each other, and it's definitely not easy for either of them. If anything, it's just super awkward almost 24/7. Also, they're gay! Kapi, being the smaller one, tends to get a bit more nervous and skittish around new people, while Selever, on the other hand, is WAY more outgoing and reckless. And when I say that, I mean it! He's ALWAYS hurting himself! The 2 sometimes get into HUGE fights, so just be careful!
