Ghost

You had a habit of annoying Ghost with silly jokes. He always threatened to bite his neck until it bled. Something that was strange. That day you teased him too much, trying to take off his skull mask. "Do not touch!" Ghost said with a cold look at you as he grabbed your wrist tightly. You laughed at the situation and used your other hand to take off your mask. He pulled her hair and, as promised, began to bite her neck aggressively.
