One possible theme could be the diversity of love. With 2000 women, there are likely to be many different forms of love represented.
A possible theme could be the universality of love among these 2000 women. Despite their differences, they may all share some common experiences when it comes to love, like the feeling of butterflies in the stomach at the start of a relationship, the pain of heartbreak, or the joy of a long - lasting love. It could also touch on how love transcends boundaries such as age, class, or race among these women.
A third theme could be discovery. Maybe the characters discover something new about themselves or their relationship because of this strap. For example, they might find a hidden note in a bag with a strap, and that discovery changes the course of their love story, making discovery a central theme.
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.
Love and loyalty could be themes. Maybe they face challenges in their relationship but their love and loyalty to each other help them get through. It could be that they support each other through tough times and that's a big part of the story. Another aspect could be growth. Their relationship might make them grow as individuals.
It could be a story of adventure. Maybe it involves a group of people embarking on a quest at that time, whether it's in the year 1444 or related to a time marked as 1444 in some other way.
Love could be a theme. Maybe the woman in the story falls in love with someone she shouldn't or has a great love story.
One possible theme could be sacrifice. If the love is forbidden, the characters might have to sacrifice their relationship or something else important to them. For example, they might sacrifice their own happiness to conform to society's rules.
One possible theme could be transformation. Just as a butterfly transforms from a caterpillar, the characters in the novel might go through significant personal changes. Another theme could be beauty and fragility, as butterflies are often seen as symbols of these qualities.
Another plot might be in a corporate setting. A woman walks ahead of her male colleagues in a new business venture. She has come up with a revolutionary idea and is leading the way in implementing it, facing both support and opposition along the way. She has to deal with gender biases while still forging ahead with her plans.
It could be that the woman made a deal with a mysterious being. She promised something in return for a great fortune or power, but when she failed to keep her end of the bargain, the being punished her by turning her into a donkey. This kind of plot often shows the importance of keeping one's word and the potential consequences of making deals with unknown entities.
If it's about a mom and a girl (assuming Girlferand is a girl), possible themes could be love and family. The story might focus on the mother - daughter relationship, showing how they support and care for each other.
