The baby could bring them closer. They'd have a new shared responsibility, which would strengthen their bond. They'd be more focused on each other and the family they're creating.
The baby could be a new focus in their relationship. Instead of just their own dreams and goals, they now have to think about the future of their child. This could lead to some arguments as they might have different ideas about how to raise the baby. But in the end, they work through those differences and their relationship becomes more stable and loving as they grow as parents.
One possible plot could be that Eren and Mikasa face many challenges while raising their baby. Maybe they have to deal with threats from outside forces who want to harm their family. They might also struggle with adjusting to their new roles as parents.
His apology might initially cause some confusion in their relationship. Mikasa has been used to a certain dynamic with Eren, and this change could throw her off. However, in the long run, it could be positive. They could start to see each other in a new light. Eren might become more protective of Mikasa in return, and Mikasa could be more open with Eren about her own desires and fears. For example, they could start to plan for a future together, something that was previously unthinkable due to the tension between them.
Well, it could start with Mikasa and Eren finding out they're going to have a baby during a time of rebuilding in their world. The story could focus on how they prepare for the baby's arrival. For example, Mikasa knits baby clothes while Eren tries to build a crib. Their friends also get involved, like Armin giving them advice on parenting based on his knowledge. And the baby might grow up with a special connection to the history of the Walls.
The main characters are obviously Eren and Mikasa. They are the ones having a baby in this fanfiction.
Eventually, Eren might start to investigate the reasons behind Mikasa's betrayal. If he discovers that there are more complex factors at play, like she was forced or there was a misunderstanding, he could feel a mix of guilt for his initial reaction and relief that their relationship wasn't as broken as he thought. However, if he finds out that she truly betrayed him out of her own will, he might become even more determined to carry out his plans, whatever they are, without her.
A fanfiction with Eren apologizing to Mikasa could be set in a post - apocalyptic world where they are trying to rebuild. Eren realizes that his actions have not only affected the big picture but also his relationship with Mikasa. He apologizes for his recklessness. Mikasa, being the strong - willed character she is, might be hesitant to accept at first, but then realizes that this is a new start for them. They could then start to work together more closely, with a new understanding and respect for each other.
In a more AU (Alternate Universe) setting, they could be in a world where the titan threat doesn't exist. They are just two normal people in a small town. Eren has been in love with Mikasa for a long time but was too shy to act. One day, during a local festival, he finally gathers the courage to kiss her under the twinkling lights.
Armin is often a popular character. He might be like a wise uncle figure to Eren and Mikasa's family, offering advice and support. Another could be Levi. He could be the strict but caring mentor to their children, teaching them important skills.
Often, in these fanfictions, Eren develops more empathy. He starts to really understand Mikasa's feelings. For example, he might realize how much his actions impact her and become more cautious. He becomes more of a protector instead of just a fighter.
A high school fanfiction about them could also involve a school project. They are paired up for a big history project about their town's past. Eren initially complains about working with Mikasa, thinking she's too serious. But as they start researching, they discover things about their families' histories that are intertwined. This discovery makes their relationship more complex and deepens their bond as they continue to work on the project.
