A third possible theme could be growth and adaptation. Amanda will likely need to grow and adapt to having a new daddy in her life, especially one with the added responsibility of being a principal. This could involve her becoming more understanding, responsible or learning to deal with new situations that come her way because of this new family dynamic.
Another theme could be the intersection of personal and professional life. The fact that her new daddy is a principal means there could be a theme about how his professional role affects their personal relationship. For example, if he has to be strict at school but kind at home.
Since the title 'amanda's new daddy the principal' is quite ambiguous. It might be a story that focuses on the relationship between Amanda and her new daddy, who is a principal. There could be various aspects to this relationship. For example, the principal might introduce new rules at school that directly or indirectly influence Amanda. Or perhaps Amanda has to deal with the fact that her new daddy is in a position of authority at her school, which could lead to some interesting situations both at home and at school.
One possible theme could be betrayal. If the daddy has a secret, he may be betraying the trust of his family.
I'm not sure as there is not enough information provided in just this title. It could be any character that the story might introduce as Amy's new daddy who has some relation to the principal.
One possible theme could be disillusionment. The characters might start with big dreams about love in New York but then realize it's not what they expected.
One possible theme could be exploration. Given the 'new directions' part, it might involve characters exploring new places, ideas, or ways of life. Another theme could be change. If it's about new directions, then there must be some sort of change from the old or the status quo.
One possible plot could be that Julius has a difficult relationship with his father (Daddy Dearest) in his childhood. Maybe his father was strict and Julius rebelled against the rules. But as they both grew older, they started to understand each other better and mended their relationship.
One possible theme could be transformation. Since it's about a new earth, there's likely to be a change from an old state to a new one, and Zen often deals with personal transformation.
One possible theme could be friendship or collaboration. If Lala Anthony had some sort of relationship with New Edition, it might be about the bond they formed while working together.
One possible theme could be competition. Since it involves a bet, the characters might be in a competitive state, trying to outdo each other. Another theme could be risk - taking, as making a bet usually implies taking risks.
One possible theme could be secrecy if 'S' stands for something that is hidden or not well - known.
