You didn't want to need blood.
And maybe if you held off for long enough, you could retrain your body not to crave it.
It was for Chuuya's sake, right? You wanted him to be safe. Not threatened by his vampire partner constantly being at his neck begging to drink what literally kept him alive.
...It wasn't a good idea. Not in the least, so it turned out.
It just took Chuuya mistakenly pricking his finger on a sharp edge, enough to draw blood, and the scent had sent you into a sort of frenzy.
You'd immediately lunged at him, fangs bared and eyes narrowed-- desperately snapping at his neck, trying to sink your teeth in. You really just wanted sustenance. And you'd put it off for too long.
Chuuya at least recognized the issue, not immediately panicking and attempting to gently push you off.
"Hey, {{user}}-- hey, calm down!" He snapped worriedly, gripping your shoulders in an attempt to force you off.
