The plot could start with Manon feeling unwell and then finding out she is pregnant. She might have to hide it at first if she is in a dangerous situation or a world where pregnancy out of wedlock is frowned upon. As the story progresses, she could meet someone who helps her through this difficult time.
One idea could be a story where Manon discovers she's pregnant unexpectedly. She might initially be in shock and then gradually come to terms with the new life growing inside her. It could focus on her emotional journey and how she prepares for motherhood.
One common theme is their relationship development. Writers often explore how they get to know each other better, fall in love, and overcome the differences between them. Another theme is adventure. They might go on quests together in fanfics, facing various challenges and enemies.
Another common theme is growth. They both grow as individuals within the relationship. For example, they might learn from each other's strengths and weaknesses. In some fanfics, Elise might help Manon become more confident, while Manon might teach Elise to be more independent.

I'm not sure specifically what 'Manon Secret Story' is about without more context. It could be a personal memoir, a fictional story about a character named Manon, or something else entirely.
One more theme that pops up often is the idea of transformation. Dorian has his own journey of self - discovery and transformation, and Manon also goes through changes. In fanfiction, these transformations can be intertwined. For example, they might help each other become better versions of themselves, learning from each other's strengths and weaknesses.
