The side story with the father was disappointing. He had a first love and gave him up so he could sleep around and have kids. He then wanted to be with him once he was done sleeping around. I felt so bad for the day care teacher. In his mind he will know he wasn't good enough to be loved for himself. He was the left over choice of a sad old man. It would have been more realistic if he rejected him.
