The family of the show is not a traditional one. The mother and father lose one of their babies and are left with twins. A doctor suggests they adopt a little boy who was left at a fire station. They do. The little boy is black and the family is white. They take him in and love him as their own anyways which is a beautiful thing. As the show progresses, we meet his father who was a brilliant musician and poet who turned to a life of drugs. The little boy, now a man with his own family hunts him down. He forgives him and begins to bond with him. Then he realizes that his mother knew who he was the whole time. Yesterday's episode (the one I watched today) teaches us something else about his father, that he had a boyfriend of sorts. That is just one part of the story. The twin sister has an eating problem which is something she had since she was a little girl. She starts going to a help group for it and meets a man she falls in love with. They break up because he quit on his diet, only he comes back on Christmas Eve and commits to his diet and to her. The show ended with something bad happening to him. The twin brother was a famous actor on a sitcom and quit because he wanted to be viewed as a real artist. He finds himself moving from california to new york city (where his adopted brother lives) and has his own issues from childhood with feeling left out unravel. Then you have the original father of the twins and the boy, who died. We don't know what happened to him yet because the story didn't reach that part yet but the mother did remarry, and it was his best friend. They have hinted at the father being abusive to the mother in one episode but didn't get in to it very deep, kind of left it open to interpretation. So as you can tell, this story has a lot going on but it has been so beautifully written.
