Perhaps in the fanfiction, Ariel and Eric get married and have to deal with the cultural differences between the underwater world and the human world. For example, Ariel has to learn the proper etiquette in Eric's kingdom while Eric tries to understand the unique traditions of Ariel's mermaid family.
Perhaps in a fanfiction, Ariel and Eric will have a family of their own. They will raise their children to understand both the land and the sea, creating a unique bond between the two worlds.
One possible fanfiction could be that Ariel and Eric discover a hidden underwater kingdom that was lost long ago. They embark on a journey to learn about its history and find that it holds the key to a magical power that can save both the underwater and land worlds from a new threat.
Often, in fanfiction, Ursula can still be a main antagonist. She might come back with a new plan to break up Ariel and Eric, maybe using a different form of magic or disguise this time.
In the fanfiction, a romantic plot could involve Ariel getting the ability to walk on land permanently. Eric then takes her on a tour of his kingdom, showing her all the beautiful places. At sunset, he takes her to a cliff overlooking the ocean and proposes to her, making it a very romantic scene.
One interesting storyline could be Ariel and Eric exploring new lands together that are beyond the sea and the shore they know. They could discover hidden islands with magical creatures and have adventures while learning more about each other's worlds.
One possibility is that they immediately start planning their future. Since they come from two different worlds, they'd have to figure out how to make their relationship work. Maybe they start building a place where both of them can be comfortable, half on land and half in the sea. And they could start spreading the message of love and unity between humans and mer - people.
After the kiss, their relationship could develop in many ways. They might start sharing their dreams with each other. Ariel could tell Eric about her long - held dreams of exploring the human world further, and Eric could share his aspirations of being a great leader. This mutual sharing would bring them closer. Also, they would likely face some opposition, especially from those who don't believe in the union of a human and a mermaid. But this would only make them fight harder for their relationship.
There are several possible reasons. Maybe she has lost something precious in the fanfiction. It could be a magical item that was important for her connection to the sea. Or perhaps she has had a fight with a friend or someone she loves. This emotional distress makes her break down in tears as she tries to deal with the situation.
Discovery is another theme. They are constantly discovering new things about each other, their cultures, and their worlds. This discovery process helps to strengthen their bond and is a key element in many ariel and eric lemon fanfictions. For instance, Eric might learn about the mermaid society from Ariel, and Ariel might learn about human traditions from Eric.
