The contrast between the two concepts. Lucifer is often depicted as this complex, otherworldly character, and a single mom represents a very down - to - earth, relatable figure. The clash and potential for interaction between them can create unique and engaging storylines.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a vast collection of fanfictions on various topics, including those related to Lucifer. Just use the search bar and type in relevant keywords like 'Single Mom' and 'Lucifer' to find the stories you're interested in.
Writers can develop the single mom's character by showing her strength. She has to manage on her own while taking care of her child, so depicting her as a capable and resourceful woman is important. For example, she could be shown handling financial difficulties with ease. Also, her love for her child should be a central aspect, like how she sacrifices her own needs for the child's well - being.
For a realistic relationship development, it should start with Thanatos observing the single mom in her daily life. He could notice how she takes care of her child, manages the household, and faces difficulties. This initial interest can then turn into a deeper emotional connection as he starts to understand her emotions and motives. They could start with small interactions, like Thanatos leaving small signs of his presence that the single mom gradually realizes are from someone or something otherworldly.
Family building is also a big theme. As Shadow gets involved with Amy, they start to create a new kind of family unit. It's about how they blend their lives together and create a stable environment for the child.
One possible title could be 'The Encounter of Lucifer and Sabrina'. It's simple and straightforward, giving a clear idea that the story is about the two characters coming together.
One common theme is the struggle of the single mom in a world that might not fully understand her situation, especially in the context of King Arthur's time. Another theme could be the relationship between the reader (the single mom) and King Arthur, perhaps how he helps her overcome difficulties.
Another interesting one could be 'Shadow's Support'. In this fanfic, Amy is a single mom trying her best to provide for her child. Shadow, seeing her efforts, decides to support her. The story delves into how their relationship changes from mere acquaintance to something deeper as Shadow helps Amy in different aspects of her life.
Perhaps the single mom has lost someone dear to her and Thanatos, being associated with death, has a connection to that loss. He is drawn to her grief and her love for her family. He tries to comfort her in his own way, and as they interact more, a relationship forms. They might go on adventures together where Thanatos shows her different aspects of the afterlife, which helps her come to terms with her loss and also fall for him.
