One aspect to consider in this fanfiction could be the extreme devotion Mikasa has in a yandere state. Yandere characters are known for their obsessive love, and Mikasa's love for Eren was already intense in the original series. In the fanfiction, this might be amplified, leading to situations where she becomes overprotective and possessive of Eren, perhaps even to the point of excluding others from his life. This could create a lot of drama and conflict, especially when Eren's own goals and relationships with other characters are taken into account.

One popular theme is redemption. Since Annie has done some not - so - great things in the original story, fanfictions might explore her journey of redemption through her relationship with Eren. Another theme could be forbidden love. Given their different allegiances in the story, a relationship between them would be considered taboo. Also, the theme of power balance is common. They both possess unique Titan powers, and fanfictions could play with how they interact with each other in terms of power, like whether they compete or cooperate.
