First, know the characters well. Study their personalities, motives, and relationships from the original source. Then, come up with a unique plot idea, like a new adventure they could go on.
To write a good Clarke Bellamy fanfic, it's important to stay true to their characters. Don't make them act out of character just for the sake of the plot. Add some emotional depth to their relationship, for example, by exploring their unspoken feelings.
First, you need to create a well - thought - out OC. Decide on their appearance, personality, and backstory. For example, if your OC is a tough survivor, give them a backstory that explains how they became that way. Then, think about how they will interact with Bellamy Blake. Will they be friends? Rivals? Lovers? Next, plan out the plot. Maybe start with a conflict that involves both the OC and Bellamy. And don't forget to stay true to the 'The 100' universe's overall tone and setting.
When writing a Clarke x Costia fanfic, you should focus on their unique connection. Maybe start with a situation that forces them to interact more closely. For example, they could be trapped in a dangerous place and have to rely on each other. Also, use vivid descriptions to bring out their emotions. You can describe how Clarke looks at Costia, the small gestures between them. And don't forget to give the story a proper pacing. Don't rush their relationship development. Let it grow organically over the course of the story.
