Well, in the 'Steven Universe' fandom, it's very likely that there are fanfictions about Steven and Pearl kissing. Since the show has such rich characters and complex relationships, fans are inspired to create their own stories. These fanfictions can range from sweet and innocent interpretations to more complex and thought - provoking ones, but they are all a part of the fans' love for the show.
There might be a fanfiction where Steven and Pearl go on an adventure to a new planet. In this story, they encounter strange new creatures and have to work together to overcome obstacles. It's a great way to explore their characters outside of the main storyline of the show.
Pearl is often very protective. She makes sure Baby Steven is safe from any harm, whether it's from outside threats or just him getting into things he shouldn't. For example, she might gently stop him from touching a dangerous Gem device.
Another reason could be the sense of community. When people write fanfiction about them, it shows that there is a community of fans who care about them. Reading fanfiction can make them feel more connected to their fans and also give them a chance to be part of different interpretations of their own stories.
There could be a plot where Baby Steven gets sick or injured in some way, and Pearl is extremely worried. She tries all her knowledge of Gem healing techniques, but since Steven is half - human, she has to figure out new ways to help him. She might seek advice from Garnet and Amethyst, and in the process, they all bond more closely as a family, with Pearl being especially protective of the baby Steven.
Perhaps a theme of acceptance. Pearl has her own past and way of dealing with things, and Steven is always so open - hearted. A kiss between them in fanfiction could symbolize Pearl accepting a new side of herself or a new type of relationship. Also, the theme of breaking norms as their relationship in the show is more of a friendship/mentorship, and fanfiction can play with changing that dynamic.
In fanfics, the Steven x Pearl relationship is interesting because of their different natures. Steven is young, full of heart and spontaneity, while Pearl is more refined and has a deep knowledge of Gem culture. Their interactions can lead to unique storylines, like Steven teaching Pearl about human ways or Pearl guiding Steven in his Gem powers.
Finding the perfect 'Steven x Pearl' fanfic can be a bit of a journey. One way to approach it is to join Steven Universe fan communities. People in these communities often share and recommend their favorite fanfics. There might be fanfics that take a creative spin on their relationship, like imagining them in alternate universes or in situations that didn't occur in the original show. By interacting with other fans, you're more likely to discover some really interesting fanfics that focus on Steven and Pearl's relationship.
