Before Tilla’s fist met Vincent’s eye, he abruptly opened his eyes and managed to grab her hand. He stopped the fist in time and protected himself from getting blue eyes, that is if Tilla's fist had that much power and precision.
Sure enough, Vincent was finally fully aware of his surroundings. He saw Tilla looking down at him with pure terror in her eyes. He looked down at his mouth and finally realized that he had been draining Tilla’s blood. He abruptly opened his mouth wide and retracted his fangs.
However, since he had made very deep puncture marks on her hand, the bleeding didn’t immediately stop. The sweet blood kept on pouring inside his mouth; Tilla was in too much of a shock and didn’t immediately pull her wrist away from his mouth.
