It challenges the norms. Flash marriages are not the common way to start a relationship, and when a unique love develops within it, it goes against the traditional view of how love should develop. These novels show that love can happen in unconventional ways and still be strong and beautiful. It gives readers a different perspective on love and relationships, which is very appealing, especially for those who are looking for something new and different in their fictional love stories.
The element of surprise. In flash marriage, the couple gets married quickly without much prior acquaintance. So, when a unique love blossoms, it's unexpected. For example, in many such novels, the husband might have a hidden side that only the wife discovers gradually, making the love story interesting.
The journey of discovery. Since they are strangers at first in a flash marriage, the process of getting to know each other and falling in love is full of exploration. The unique love in these novels often shows how two people with different backgrounds and personalities come together and form a deep connection. It's like a puzzle coming together piece by piece as they learn about each other's likes, dislikes, dreams, and fears. This exploration makes the love story more engaging than a traditional love story where the couple already knows a lot about each other from the start.
