In general, Snow White with the Red Hair follows the manga quite faithfully. There may be a few minor tweaks for the sake of animation or to enhance the story's presentation, but they don't deviate significantly from the manga's essence.
The ending of Snow White with the Red Hair manga has a touching resolution. The main characters find their happiness and the story wraps up in a satisfying way.
Another way is to explore her emotional connection to the lemons. Maybe the lemons remind her of her mother who used to make lemon pies. So when she is in a difficult situation, the thought of the lemons and her mother gives her the courage to keep going. This would add more depth to her character.
One idea could be exploring an alternate universe where Snow White is a powerful sorceress instead of a princess. She could use her magic to protect the kingdom in new and exciting ways. Another idea is a time - travel fanfic, where she goes back in time to prevent the events that led to her current situation. And a third idea could be a story where she teams up with other fairy - tale characters from different stories to fight a common enemy.
