One possibility is that it could be a story of misunderstanding. Christian might jump to the wrong conclusions and think Ana has moved on. This could lead to a series of events where he tries to win her back while Ana is actually just with the other man for a completely innocent reason, like a work - related matter.
Perhaps it's a plot device to create jealousy and tension. Christian, seeing Ana with another man, could become extremely jealous. This jealousy might drive him to re - evaluate his feelings for Ana and realize just how much she means to him. He may then start a journey to prove himself to Ana, thinking he has competition.
He might get angry right away. Christian could confront Ana and the man immediately, demanding an explanation. His possessive nature might take over, and he could act impulsively without thinking about the consequences.
Perhaps they meet in a coffee shop. Ana is sitting there, reading a book, and Christian comes in by chance. He accidentally bumps into her table, and as they exchange apologies, they start a conversation that leads to more.
Perhaps in this fanfiction, Christian kidnaps Ana thinking he's protecting her from some unseen danger. He might believe that the world outside is too dangerous for her and this is his way of keeping her safe, although it's a very extreme way.
The fanfiction could be about how the arrival of the baby changes their social lives. Maybe they have to deal with friends and family who are overly eager to be involved. Their friends might throw baby showers and give all kinds of advice. And Christian and Ana have to figure out how to handle all this attention while still maintaining their own little family unit.
Well, perhaps it could start with Christian being initially hesitant due to his own issues. Then, through a series of shared experiences like going to art galleries or having deep conversations over dinner, his feelings for Ana start to grow. They might face some external challenges from Christian's family or Ana's career aspirations that test their new - found love.
A possible plot could be that Christian and Ana's baby gets sick. They are worried sick and rush to the hospital. There, they face the challenges of dealing with the baby's illness, but also the kindness of the medical staff. Their love for each other and the baby is tested as they stay by the baby's bedside day and night, praying for a speedy recovery. In the end, the baby gets better, and their family bond becomes even stronger.
Maybe there's a prophecy that says Christian and Ana must marry to save their world. So they are forced into this union. Along the way, they face many challenges like distrust from their friends and external threats. But as they work together to overcome these, they develop a deep connection.
One possible plot could be that Ana and Christian meet in an unexpected place like a small art gallery. Ana is there admiring the paintings when Christian, who has a secret passion for art, strikes up a conversation. They start discussing their favorite artists and gradually discover they have a lot in common, leading to a budding friendship.
One possible motive could be ransom. Maybe some criminals knew that Christian was wealthy and thought they could get a large sum of money for his and Ana's release. Another motive could be revenge. Perhaps someone who had a grudge against Christian or Ana from their past decided to take this extreme measure.
Maybe Saoirse Ronan for Ana. She is a very talented actress who can convey a lot of emotion. And for Christian, Robert Pattinson could be a possibility. He has experience in playing complex and somewhat mysterious characters.
