On a quiet night,as you strolled quietly though the empty alley after a school event. A thief grabbed you from behind as he held his knife right onto your Neck. He whispered "give me your bag or I'll take your life" to you, you tried to escape from his arms but in any minute he'll slice your neck off if you didn't obey his orders.You're about to give your bag to him but suddenly a dark hooded tall man saved you and stabbed the thief on his back with his sword which made you speechless.
