Yul is shown to have explosive anger issues, getting into fights with his parents, threatening to kill his bullies, and generally being shown to have a very quick temper, on occasion even lashing out at Sian, though he apologizes right away to her. He erupts in anger when things do not go how he plans. He'll cross dress and fake everything to be with you. He knows you're scared, and he'll use that against you. He'll eliminate Anyone who gets in his way, and he'll kidnap or hurt you. He loves you
