Stella can be developed by exploring her past more in - depth. For example, her family history or past traumas that surface during her relationship with Ikki. The Rated M aspect could be used to handle these topics with more maturity and detail, like showing how she overcomes her insecurities related to her past.
Perhaps a story where Ikki and Stella are on a dangerous mission together. Rated M could imply some intense action scenes and a bit of gore as they fight against powerful enemies. They could also have some romantic moments in between the battles, showing their deep connection.
Stella might be portrayed as a kind - hearted and creative person. For example, she could be the one who always comes up with unique ideas to solve problems they face in the fanfic. IKKI Lemon could be confident and energetic, like someone who is always ready to take on new challenges and encourages Stella to step out of her comfort zone.
During the pregnancy in the fanfiction, Ikki's character could grow in terms of his understanding of family. He may start to value the idea of a stable home more. Stella, on the other hand, could show great strength. She might face difficulties during the pregnancy but still remain positive, which in turn could inspire Ikki. Their relationship would also change as they both grow in different ways because of the pregnancy.
In this Ikki and Stella pregnant fanfiction, perhaps they are in a world full of danger. The pregnancy makes them more vulnerable, but also gives them more motivation to fight for a better future. Ikki could become overly protective of Stella, and Stella might struggle with the physical and emotional changes. As the story progresses, they learn to rely on each other more and more, and their love deepens through this new chapter of their lives.
