The next couple of weeks had passed in relative normality; though there were definitely some scary moments where you had done something to tick them off, the Mukamis weren't nearly as reactive as the Sakamakis. You didn't know whether it was due to them being human once upon a time or the fact that they tended to interact with each other instead of constantly making it their business to torture you, but you felt you were settling in pretty well. You were currently with Ruki, helping him dust the books in the substantially sized library, and thus far it had been going along in a mildly companionable silence. You had found that Ruki generally preferred the 'livestock should be seen and not heard' mentality, something which you didn't really mind all that much. Still, there was just one thing wrong...
"Ah! Ruki this h-hurts!" You gasped, and he gave a low chuckle, hands sliding up your sides as he leaned in close, breath dusting against your pulse.
"You can't even manage this much?" He questioned, and you gave a groan, dropping your hand back to your side, fingers tingling from your overreaching.
"It's too high up! You always choose the books literally just out of my reach―" you gave a huff, shoulders slumping. "I hate this stupid penalty game of yours."
"Then you give up?"
"Yes," your voice was heavy with defeat and he pushed you face forward against the shelf, pulling your collar aside and sinking his fangs into your shoulder with a moan, taking only a couple of gulps before letting you go, your knees feeling slightly spongy. Though he hadn't taken much, the bites had accumulated largely.
"That is seven for me and...oh, none for you." He murmured, stepping around you and pulling the book down, reading the title. "Lovecraft, interesting. Let us head over to the mythology section, then."
"You are enjoying this far too much." You snapped, following him to a new section of the library and picking a bookcase, dusting the shelves one by one. The way the library was arranged was odd in itself; that Lovecraft compilation had - for some bizarre reason - been in the non-fiction area; you hoped it was due to an accidental placement or a random system that only Ruki could figure out because Lovecraft being true was really the last thing you needed. You came across a huge book labelled 'Greek Mythos' and you cleared your throat, holding it up for Ruki to see. "If I open this book and Zeus is mentioned on either page I get to bite you."
"That is...quite sly of you, livestock. You're learning." He said, gesturing for you to go ahead. You opened it about a tenth of the way through to a story describing how Zeus tricked his wife into marrying him, and you showed it to Ruki with a grin. He sighed heavily, removing his jacket and approaching you with a slightly anticipatory expression; you had actually gotten very proficient at using your fangs - though they weren't as long as a full vampire's - and you found that they didn't exactly hate it when you bit them, though really you wished they would keep quieter. Kou was quite the moaner, much to your eternal embarrassment, and you were sure he put it on just to make you uncomfortable. Still, his blood was deliciously sweet and crisp, so you let it slide. You did feel slightly nauseous at the fact that you were assessing them by how their blood tasted, but there were still oceans between you and the vampires that only saw you for your blood, be they Mukami or Sakamaki.
"Ok...so if you'd just...sit down please?" You requested, not wanting to stand and bite him; you weren't that good yet. He sat without a fuss and you took his hand, turning it up to show the inside of his wrist.
"Not there." You looked up in alarm as he tugged his arm away to pull his shirt aside slightly, tapping the back of his shoulder.
"But I've never—"
