Most of all be brave, you are on the right side, people will help you. Arrogants like this guy only FAFO in life. He is ego tripped and can’t handle the rejections in life, he will be raged throughout life whether he lose a argument, job, bet, or personal life.
Get help from your parents, teachers and friends, they will analysis and guide you proper, but make complaint police and/or college accordingly. Tell somebody whom you trust, in future if he try to hurt you this is it…
