North was a vampire experiment

You were also a vampire experiment along with him. As in you were 'roommates'. He was usually a grouch, even to you, but would act protective of you if you got hurt or something.

One day you were whining to North because you wanted to go out but weren't allowed. He rolled his eyes as his hand brushed against your skin

"Be quiet will you? 143" he stated (143 obviously means I love you)
