The plot might involve them moving to a new city as a married couple. There, they meet new friends and new enemies. Misaki could get a great job opportunity, but it means she has to work long hours. Usui supports her through this, but then he starts to feel a bit left out. This creates some tension in their relationship which they then have to resolve. It would be a story of growth and love in a new environment.
Love and support are common themes. Usui would likely be very supportive of Misaki during the pregnancy, showing his deep love for her. Another theme could be anticipation. They would both be anticipating the arrival of the baby and all the changes it will bring to their lives. Family is also a theme. They may have to deal with their own families' reactions and build their new family unit.
Well, in many Misaki and Usui kiss fanfictions, the authors often focus on the intense emotions leading up to the kiss. It's a moment that's highly anticipated by fans of the couple. The kiss can symbolize the deepening of their relationship, which might have started from a more antagonistic or hesitant beginning in the original story.
There are several. For instance, 'Forbidden Feelings' is a fanfiction that plays with the idea of them having to hide their relationship at first. It has some really interesting twists and turns. 'Heartbeats in the Rain' is a very emotional one. It shows how they support each other through tough times and also has some lovely romantic and a bit steamy scenes. 'Destined to Be' is another great one where it seems like fate is constantly bringing them together in the most unexpected ways.
Archive of Our Own (AO3) is also a great place. It has a well - organized tagging system. So, if you search for 'usui hurts misaki' in the tags or the search bar, you'll likely come across some good reads. Plus, the community there is quite active and friendly.
Another great one could be 'Usui's Hidden Pain'. Here, Usui is dealing with some family issues that he doesn't share with Misaki at first. But when she finds out, she feels hurt that he didn't trust her enough. The story unfolds as they work through this together and their relationship evolves.
One great fanfiction could be titled 'Usui and Misaki's Blissful Union'. In this story, it might start with Usui planning a grand, yet intimate proposal for Misaki. It could show their journey from being just two people in love to actually tying the knot. There would be all the sweet moments like choosing the wedding dress together, and Misaki blushing as Usui tells her how beautiful she looks. Their friends would be involved, with everyone being excited for their big day.
