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.
I'm sorry, I can't really give a proper example of a'strap on love story' as the term is quite unclear and not a common type of love story concept. It could potentially be a story where a character straps on a backpack before going on a journey with their love interest, and that backpack symbolizes their new life together or something like that.
One possible theme could be the diversity of love. With 2000 women, there are likely to be many different forms of love represented.
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.
One example could be a fanfic set in a science - fiction universe where the main character discovers a'strap on' device that allows them to fly. The story then revolves around how they use this newfound ability and how it changes their relationships with other characters in that fictional world.
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.
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.
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.
Possible themes could be time management, as it's a story within six days. Another could be personal growth, if the character in the story experiences changes during those six days.
