First, understand the characters well. Kara is kind - hearted and protective, so your OC should interact with her in a way that makes sense for her personality. For example, if your OC is more brash, there could be some initial conflict that then develops into a deeper connection.
One popular plot theme is the unlikely alliance between Connor and Kara. They come from different paths in the game's world, but in fanfiction, they might team up to protect other androids. For example, they could work together to rescue a group of androids from a dangerous situation in a CyberLife facility. Another theme could be the exploration of their emotions towards each other. As androids starting to feel, they might develop a unique bond that goes beyond just friendship or comradeship. It could be a slow - burn relationship where they gradually understand each other on a deeper level.
Fanfiction.net is also a great place to look. It has a large collection of fanfictions for various fandoms, including Detroit: Become Human. However, the quality can vary, so you might need to skim through a few to find ones that really focus on the OC x Kara relationship in a way that you like.
Writers often start by having Connor and Kara meet in a tense or unexpected situation. This could be during a raid on an android hideout where Kara is hiding with Alice and Connor is initially there to investigate. From there, they gradually start to see each other's point of view. As Connor begins to deviate, he realizes that Kara's actions are out of love and protection, not just simple disobedience. This shared understanding forms the basis of their relationship development.
One great 'Detroit: Become Human' fanfiction is 'The Android's Journey'. It delves deeper into Connor's character development post - game events. It shows how he continues to adapt in a world that is still adjusting to the presence of androids. Another interesting one is 'Markus' Rebuild'. This fanfic focuses on Markus' efforts to truly integrate androids into society, exploring the political and social challenges he faces in a more detailed way than the game. And 'Kara's New Family' is a heart - warming fanfiction that follows Kara as she creates a new life for herself and Alice, away from the chaos they initially escaped from.
