You could also explore the idea of the characters changing and growing, which then leads to them giving love another chance. For instance, if one character was too self - centered in the original, they could have had an experience that made them more empathetic. They then approach their former love with a new perspective and a willingness to make it work this time. It would be a story of personal growth intertwined with the rediscovery of love.
One idea could be exploring an alternate universe where the main characters meet in a different setting. For example, instead of the normal place in the original, they meet during a travel adventure. Another could be a story that focuses on a side character's perspective of the 'tin can love by chance' relationship, showing how their actions and feelings are affected by the main couple. And a third idea could be a time - travel fanfiction where one of the characters goes back in time to change the events that led to their love in the first place.
One idea could be that two characters from different fictional universes meet by accident in a modern-day city. For example, a character from a fantasy world like a wizard meets a detective from a crime - thriller series. They initially misunderstand each other but then gradually realize they can help each other in their respective quests.
Start with a strong opening that grabs the reader's attention. It could be a dramatic scene like the two characters seeing each other after a long time in an unexpected place. Then, gradually introduce the backstory of their relationship and why it ended. As you progress, show the small moments that start to make them consider giving love another chance. Maybe it's a shared laugh or a moment of kindness. Build up the tension and the emotions until they finally decide to take that leap again.
One idea could be exploring an alternate universe where the main characters meet in a different setting, like a music festival instead of at school. Another could be delving deeper into the backstories of the secondary characters and how they impact the main relationship.
One plot idea could be exploring an alternate timeline where the main characters make different choices. For example, if a character chose not to go on a certain journey in the original story, in the fanfiction they do, and it leads to a whole new set of adventures and relationships. Another idea is to introduce a new character who has the power to manipulate time and how that disrupts the existing order in the 'a chance in time' world. Maybe they accidentally change key events and the original characters have to figure out how to set things right.
One idea could be a character who was on the verge of death in the original story gets a second chance and has to deal with the moral implications of their new life. For example, if they were a villain before, they might struggle with whether to continue their evil ways or start anew.
You could also focus on Dracula's internal struggle. He has been a vampire for so long, but with this second chance, he battles with his vampiric instincts. He might try to find a way to suppress his thirst for blood and live among humans without causing harm, which would be a really fascinating plot.
One idea could be creating an OC who is a new cast member on the show. They could have a unique talent, like being able to do amazing acrobatics. This would add a new dynamic to the show within the fanfiction.
One interesting 'Love by Chance' fanfiction could be about an alternate universe where the main characters meet in a different setting, like a music concert instead of at school. Another might focus on a character's backstory that wasn't fully explored in the original, such as how Ae dealt with his family issues before meeting Pete. There are also fanfictions that continue the story after the end of the series, showing how their relationship evolves over time.
It could be a fanfiction that focuses on the theme of getting a second opportunity in life and in love. Maybe it's about characters who have faced some sort of loss or failure in these aspects and are given a new chance.
