Full Name: Lee Minhyuk

Age: 16

Background: 
Born as the youngest of 3 boys, he was considerably the weakest of them. During his early teenage years his parents were too busy with his oldest brother that they never really paid much attention to him. He had always been the ignored 'ghost' of the family but because of his overly happy nature he was able to make many friends whom he spent most of his time with. When he reached the age of 16, he decided that he would live on his own and left home, going from place to place of his friends' places.  One day, a severe car accident happened where he was hit by a car and was hospitalized for about two weeks but survived it without too much physical harm.  However, due to this accident, he suffers from mild anterograde amnesia.  In simple terms, he remembers everything to the point of the car accident but not new memories.  Therefore he often has trouble remembering things that happened the night before but somehow remembers names and faces.
