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.
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.
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.
One possible plot could be that Eren and Mikasa have a simple and peaceful married life. They might build a small house near the ocean. Eren could be fishing to support their family while Mikasa takes care of their home, cooking delicious meals and tending to a small garden. They would have quiet evenings together, reminiscing about their adventures in the past.
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.
The relationship might also be depicted as a source of inspiration. Eren's Titan form could inspire Mikasa to be even more fearless. She could see his strength and determination in that form and strive to match it. And in return, Eren could be inspired by Mikasa's unwavering loyalty. This mutual inspiration could drive the story forward, with both of them growing as characters throughout the fanfiction.
One great Mikasa and Eren fanfiction is 'A New Beginning'. It shows an alternate universe where they start their relationship earlier. The story beautifully portrays their deep connection and the challenges they face together. It's a really engaging read for fans of the pair.
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.
