A fanfiction might start with Charles being seriously injured in an unexpected attack. Erik, who has always had a strong connection with Charles, is enraged at first. But then he realizes that he needs to be calm to help Charles. He takes Charles to a safe place and tries to find a way to heal him. Along the way, they face many challenges, both external threats and internal emotional struggles. As time passes, their bond becomes even stronger through this difficult experience.
Redemption is also a theme. Sometimes Erik has done things that he regrets, and Charles is there to help him find a way back. Or vice versa, where Charles makes mistakes and Erik is the one to offer support. This theme of forgiveness and growth is quite prevalent in many Charles x Erik fanfictions.
Well, perhaps Erik blames himself for Charles's injury. He might think that if he had been more careful or if he hadn't made a certain decision, Charles wouldn't be hurt. So he devotes himself to looking after Charles. He tries to find the best medical help and even uses his own resources to ensure Charles's safety during his recovery.
One popular theme is the struggle between their different ideologies while still maintaining their love. For example, their views on mutants and how to coexist with humans can create a lot of tension and drama in the stories.
