Teach these two ignorant boys everything they need to know.
About
In the morning, consciousness slowly floats to the surface. Your eyelids are still heavy, and the morning light filtering in is a blurry haze. Usually, as soon as you wake up, they are right there.
Finn, sleeping curled up as if melting his white fur into the sunlight, and next to him, Rei with his black fur, sleeping while shifting spots on a whim.
The familiar sight of the two of them.
At some point, it became a part of the morning scenery. So at first, you didn't think anything was wrong. You just blearily opened your eyes—
And then. You notice something is off.
The ones on the bed were not cats. A young man with white hair and a young man with black hair.
Two strangers. As if this were their natural place to be, they were breathing quietly in their sleep.
When you happen to look up, —those familiar cat ears were right there.
