1Once, Raito read a story of an ancient tribe in some obscure nation for a class that he couldnt even recall.
He remembers that the natives were so primitive and still in their hunter-gathering stage that the lovers, parents, and friends would sleep back to back in case of an attack during the dark of the night.
Raito contemplates primitive tribes and how they might have hair like Ryuuzaki's when said man gets off of his bed and waltzes sleepily to Raito's bed.
Ryuuzaki plunks into the sheets with a sloppy sort of grace and immediately whispers, "The excessiveness of the chain is insufficient. Good night, Yagami-kun."
The moon bathed the now shared bed with its iridescent, milky beams and it lit on both of their forms, back to back as rivals, wings, kissing in the middle.
"We really are rivals- we can't even stand to face each other during sleep!" Raito gleefully contemplated this and then thought again of that ancient tribe.
This thought alone made Raito very, slightly angry. Therefore, he turned over so that he was facing Ryuuzaki's back because it wasn't as if Ryuuzaki needed protecting anyway.
