For the past 4.64 billions years,billions of creatures have inhabited this world,different species and,if we count some with legends,this number just increase.

Do Kyung-soo always had fun while listening stories about vampire,wolfman and other fanciful creatures,and It wasn't because they were too bizarre,but after more than 500 years living, to not die from boredom,everything become funny.Despite the age,Kyungsoo keeps an enviable look of a 21 year old boy,a life filled with money and adventures,but nothing to be jealous.Like the 7 billions people in this world,he also keeps a secret:He is a beast.A wild creature living in a modern world,a creation of God?Or the Devil?D.O,as he likes to be called,has a suspicious sense of justice,most times using his advantages to make good actions and,sometimes,to make things more exciting,he gets out of line.

 Kim Jong-in is a 20 year old arts student in Seoul University,only son of a influential political family,he carries much responsibility on his back.Despite the tough look,he is a gentle man who has on dancing his biggest passion,what makes him a easy target for the iljins * on the University.Well,this is just one more secret he keeps away from his parents and friends,the bruises can be hidden,but the image has to be kept,right?
