Well, the plot might involve Pearl having some sort of quest or task related to the Mystery Girl. Maybe the Mystery Girl has a special power or knowledge that Pearl needs for something important in the Steven Universe world. Pearl then has to gain her trust. They could go on adventures together, with Pearl protecting the Mystery Girl from various threats. Along the way, they develop a deep friendship and learn a lot about each other's pasts.
One possible plot could be that Pearl is initially very curious about the Mystery Girl. She might observe her from a distance, trying to figure out her habits and what makes her so mysterious. Then, they could accidentally meet, and at first, Pearl is a bit clumsy in her interaction due to her own insecurities. But as time goes on, they start to bond over shared interests like music or art. The Mystery Girl could introduce Pearl to new aspects of human culture that Pearl has not fully experienced yet.
The fanfic could be about Pearl's internal struggle regarding her feelings for the Mystery Girl. Pearl has always been dedicated to Rose Quartz, and now she's facing new and different emotions. She might be hesitant to get close to the Mystery Girl because she's afraid of changing or betraying her past loyalty. However, the Mystery Girl is so alluring and kind that Pearl can't help but be drawn to her. As they interact more, Pearl gradually realizes that it's okay to have new relationships and experiences.
Pearl could develop greater courage. In the face of new and unknown situations with the Mystery Girl, she has to be brave. This could transform her from being a bit timid in new social situations to being more confident. For the Mystery Girl, she could develop a sense of loyalty towards Pearl. At first, she might be just a curious figure, but as they go through various events together, she becomes a steadfast friend to Pearl, willing to stand by her side no matter what.
One idea could be that Pearl and Mystery Girl team up to solve a mystery on Earth that involves Gem technology. Maybe they find an ancient Gem artifact that is causing strange phenomena, and they have to figure out how to stop it together.
Well, it could be about the unique relationship between Pearl and Amethyst being extended to their gemlings. Maybe it shows how they raise the gemlings together, teaching them different things based on their own skills and experiences. For example, Pearl might teach the gemlings about grace and precision, while Amethyst could show them how to be more in tune with their wilder sides.
Perhaps she's a time - traveler from a future where the events in Steven's world have led to some big changes. She could be on a mission to prevent a certain catastrophe from happening, and her presence in Steven's time is a crucial part of that plan. She might have knowledge of future events and technologies that seem strange to Steven and the others.
A possible element in such a fanfiction could be a hidden gemstone in the mystery girl's navel. It could be a new type of gem that has powers unknown to the Crystal Gems. The story could revolve around the discovery of these powers and how they affect the balance in the Steven Universe world.
One possible plot could be that the OC is a new arrival in town. Peedee, being the friendly and curious guy he is, decides to show the OC around. They start to bond over their shared love for the local food, which Peedee's family owns a shop for. As they spend more time together, they encounter some of the Gem - related adventures that are common in Steven Universe. And through these experiences, their friendship deepens and they might even face some challenges together that test their relationship.
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.
I haven't read this specific fanfic yet. But generally, in 'Steven Universe' fanfics, Pink Pearl often plays an interesting role. If the 'lemon' in the title refers to a certain kind of fanfic trope, it might involve some more intense or emotional situations. Maybe this fanfic explores the character of Pink Pearl in a new and unique way, perhaps her relationship with other characters in the Steven Universe world.
The plot might involve a competition to see who can get the most customers in a month. Steven could be the judge, trying to be fair but also having his own favorites. There could be some sabotage involved too, like one character stealing another's secret recipe. Or perhaps a new character comes to town and opens a restaurant that threatens to put them all out of business, so they have to team up to save their restaurants.
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.
