Yes, there might be some. Some fanfiction writers focus on creating non - violent and family - friendly scenarios even with such a dramatic plot point. They could write it in a way that Misaki Ayuzawa is kidnapped but then rescued through clever means and positive relationships in the story, without any inappropriate content.
One common theme is the transformation of her character. Usually, Misaki is known for her tough exterior, but in pregnancy fanfictions, she often shows a more vulnerable side. Another theme is the support system around her, be it her family, friends or partner.
One interesting fanfiction could be 'Misaki's New Chapter' where the story delves into how she copes with the pregnancy while still maintaining her strong personality. It shows her facing challenges and also the support she gets from her friends and family.
One common plot twist could be that the kidnapper turns out to be someone she knows in disguise. Maybe it's an enemy from her past who has a hidden agenda. Another could be that she is kidnapped as part of a bigger scheme to get to someone else she cares about.
Perhaps the story could revolve around how they prepare for the new baby. Usui and Misaki could be seen shopping for baby supplies, decorating the nursery, and going to doctor's appointments together. This would show their growing bond as they anticipate the arrival of their child.
Well, a plot might be set in a future time where they are married and dealing with the challenges of married life while also trying to balance their careers. Maybe Usui has a job opportunity overseas and they have to decide whether to take the risk or stay put. Or perhaps a story where Ayuzawa is in trouble at work and Usui has to use his charm and intelligence to get her out of it, strengthening their bond even more.
He could take on more of the household chores. Since Misaki might be feeling tired or unwell at times, Usui would cook for her, clean the house, and do the laundry to make her life easier.
I think Hinata could be a great addition. He could be the comical sidekick who always gets into funny situations and in the process, either helps or hinders Usui and Ayuzawa's relationship. Another good character could be Ayuzawa's mother. Her presence could add some family drama, like she might not initially approve of Usui for her daughter.
One popular ayuzawa and usui fanfic might be the ones where they go on adventures together outside of their school setting. For example, they could be traveling to a foreign country and facing new challenges while also deepening their relationship.
Misaki Usui in 'misaki usui lemon fanfiction' typically shows a great deal of loyalty towards the love interest. He might be portrayed as a bit of a rebel in some aspects, but when it comes to matters of the heart, he is deeply committed. His good looks are often described in detail, from his tousled hair to his piercing eyes. And his sense of humor is also a big part of his character, using it to break the ice or ease tense situations in the story.
