Well, in some fanfictions, Bella might be scared of Edward because of his vampiric nature. His superhuman strength and speed could be intimidating. Also, the unpredictability of his actions as a vampire who is constantly fighting his bloodlust could make Bella feel scared.
In some fanfiction, Edward might be mean to Bella to create drama. Writers may use this as a plot device to add tension to their relationship. For example, it could be due to some misunderstanding or an external threat that makes Edward act out of character and be mean.
In this fanfiction, the relationship between Bella and Edward is turned on its head. Bella's role is now to shape Edward's character from a young age. Their interactions will be less about the intense passion of the original story and more about the tender, sometimes difficult, bond between a mother and son. She might worry about his future, his choices, and his safety in a way that is very different from the love - based concerns in the original narrative.
Their relationship develops as Edward imparts his knowledge to Bella. Since he's her master, he has a certain authority. But as time passes, Bella might start to question some of his decisions, which adds tension and also deepens their relationship as they work through these issues.
In many such fanfictions, Edward might use his superhuman speed to reach Bella just in time. He could have sensed her danger through his vampire instincts and dashed to the cliff edge, grabbing her before she falls.
Alice is often a very popular character. Her ability to see the future can add an interesting element to the wedding planning. For instance, she might foresee some problem with the wedding dress or the weather on the big day and try to prevent it. Jacob also makes an appearance in some fanfictions. His presence can create some tension as he still has feelings for Bella.
Well, it makes their relationship more paternal. Edward becomes more of a guiding force rather than just a love interest. He might scold Bella when she does something dangerous, like in the original when she gets into trouble with vampires, but in a more fatherly way.
For Edward, there's likely a mix of relief and fear. Relief because he's finally expressing his deep love for Bella, but fear because he's exposing his true feelings and also worried about how this will change things. For Bella, she's probably mostly filled with excitement and a bit of shock. The excitement of this new level of intimacy with Edward, and the shock that this moment she might have dreamed of is actually happening.
Alice is often quite popular. She has the ability to see the future, which can add a lot of interesting twists to the story. For example, she might see a danger coming towards Bella and Edward and try to prevent it. Her quirky personality also makes her a favorite among fans.
Carlisle is another character that many might like. As Edward's father figure, he can offer wisdom and guidance to the newlywed couple. His calm and ethical nature can play an important role in helping Edward and Bella navigate any difficulties that come up in their married life, such as dealing with vampire politics or ethical dilemmas.
