Hypoglycemia

“Yuu-chan, I told you that I’m okay.” he said, trying not to let his voice break.     “Cut the crap Mika. Your hands are practically shaking.” Yuu shot back.     “Well that’s-“     Yuu flicked the blond’s forehead. “You can’t do anything to change my mind. I already told you, my blood is all yours.”     “That’s not it. I just…” Mika trailed off. “I hate doing this to you.” He balled his hands into fists. “What if one day I can’t control myself and end up killing you?”     Yuu tucked a blond curl behind Mika’s elegantly pointed ear. “You won’t. I know you wouldn’t try to hurt me intentionally. So please…” A soft smile appeared on his face. “Let me take care of you.”(Or, in which Mika is a type one diabetic and his blood sugar is low. Being the self-sacrificial bastard he is, he won't take Yuu's blood no matter how much pain it causes him.)
