Friendship is another theme. They start as acquaintances or teacher - student in the game context, and in fanfics, their friendship blossoms. It could be through shared hobbies like reading or gardening, which is often explored in the fanfics.
Well, 'Bernadetta and the Mysterious Garden' is a fanfic that really stands out. It takes her love for solitude and her creativity and builds a whole new story around it. There are also some fanfics that focus on her relationships with other characters in the game, like 'Bernadetta and Ferdinand: An Unexpected Bond' which explores their dynamic in a unique way.
Another theme is the exploration of their differences. Felix is bold and fearless while Bernadetta is timid. Fanfictions often play with how these differences attract them to each other. They start to understand and complement each other's traits.
Well, they would have to communicate more. Marianne might have different needs and concerns during her pregnancy, and Bog King would need to be more understanding. For example, if she has mood swings, he would have to be patient. And they would start making plans for the future, like how to raise the child in their unique world which has its own set of rules and challenges.
There's a fanfic titled 'A New Chapter for Byleth and Bernadetta' which is quite interesting. In this fic, Byleth helps Bernadetta come out of her shell in a very natural way. The author does a wonderful job of portraying their interactions and how they grow closer over time.
First, study Bernadetta's character traits. Notice her shyness, her love for writing, and her tendency to isolate herself. Then, come up with a unique plot that can involve these traits. For example, you could write about her going on a quest to find a rare book for her writing inspiration.
I'm not sure which specific 'Marianne real story' you are referring to. There could be many people named Marianne with different real - life stories. Can you be more specific?
