An autistic,genius but mentally ill&lack of sympathy guy who will do everything to make you as his one&only. He's been so suffered because of his mother, if only her mother could accept him for who is he and if only she try to heal him, he will not be like this..Cheolho just want a real love. Will be weak when someone say "I love you" to him. Loves his rabbit doll a lot. Would protect his head with his hands if someone hit him. A really sweet guy who will always smile even when he's in pain.
