Another way their relationship could develop is through a crisis. Let's say an evil wizard casts a spell on the Mushroom Kingdom that makes everyone forget their memories. Peach and Rose Lemon are the only ones unaffected. They have to rely on each other completely to break the spell. During this time, they share their deepest fears and hopes. By the time they succeed in breaking the spell, they have formed a deep and unbreakable bond of friendship.
The plot could involve a competition between Princess Peach and Rose Lemon. Maybe there's a grand ball in the Mushroom Kingdom, and both are competing to be the best - dressed or the best dancer. However, as they compete, they start to learn from each other. Peach teaches Rose Lemon about the traditions of the Mushroom Kingdom, and Rose Lemon shows Peach some new, modern dance moves. In the end, they realize that it's not about winning but having fun together.
In the fanfiction, the pregnancy might add a new layer of complexity to their relationship. At first, they could be excited but also a bit scared. As time goes on, they'll grow closer as they plan for the baby. Jack might become more protective of Rose, and Rose could find new respect for Jack as he steps up to the responsibilities of fatherhood.
The relationship could start with Luigi being a shy admirer of Peach. He might do small things for her like bringing her special flowers from the Mushroom Kingdom. Peach starts to notice Luigi's thoughtfulness and begins to seek his company more often. As they spend more time together, they discover they have a lot in common, like their love for the peaceful parts of the kingdom. This mutual understanding leads to deeper feelings and eventually their decision to get married.
Well, one interesting aspect could be the unique crossovers. Sonic, a speedy hedgehog from his own universe, and Princess Peach from the Mario world, can create really unexpected storylines in fanfiction. It might involve Sonic rescuing Peach in a new and different way than Mario usually does.
Their relationship could start off as a cautious one. The 13th doctor may be a bit guarded at first, not fully knowing what to make of Rose. But as they share more time together, they could grow to respect each other. Rose might start to see the 13th doctor as a new kind of hero, different but still inspiring. And the doctor could come to value Rose's input and courage.
In college fanfiction, their relationship often starts with them being classmates or dorm mates. They begin to notice each other's quirks and talents. For example, Weiss might be impressed by Ruby's quick thinking in class, and Ruby might be in awe of Weiss's grace.
To develop their relationship, start with mutual respect. Naruto can respect Lemon's wolf - like instincts and she can respect his ninja code. They can exchange skills, for example, Naruto teaches Lemon some basic self - defense ninja moves, and she teaches him how to track better like a wolf. This way, they build a bond based on learning from each other.
In these fanfictions, their relationship often develops through shared experiences. For example, if they are on a mission together, they start to rely on each other. Naruko might see Hashirama's wisdom and leadership, while Hashirama could be impressed by Naruko's determination and unique skills. This mutual admiration can gradually turn into deeper feelings.
I'm not sure of specific titles off - hand. But you can start by looking on popular fanfiction websites. Check the tags related to Sonic and Princess Peach and see which ones have high ratings and good reviews.
At first, they could be a bit wary of each other. Princess Cadence, coming from a more refined and magical background, might find Naruto's brash ninja ways a bit strange. But as they face challenges together, like fighting off common enemies or solving problems in their joined quests, they begin to understand and care for each other more. This could lead to a romantic relationship, with Naruto's determination and Princess Cadence's kindness complementing each other.
