There could be a fanfiction where the Reader is a healer - type quirk user. Todoroki gets seriously injured during a battle, and the Reader is the only one who can save him. After that, Todoroki feels indebted to the Reader and they start spending more time together. This time together leads to them realizing their feelings for each other as they engage in activities like visiting the hospital for Todoroki's follow - up treatments and having conversations about life and heroism.
Here's a plot idea. The reader discovers a hidden power within themselves that is somehow related to Peridot's gem abilities. They then embark on a journey to understand this power better, with Peridot as their guide. As they travel and face various challenges, they grow closer as friends. Another plot could be that the reader is a gardener and they introduce Peridot to the beauty and importance of plants. Peridot then helps the reader create a unique garden using her technological skills.
Perhaps a plot where Todoroki gets injured during a fight and Momo has to take care of him. In the process, she discovers a more vulnerable side of him. Meanwhile, Todoroki is impressed by Momo's nurturing side. This could lead to them exploring their feelings for each other as they spend more time together.
Another plot could be that the reader discovers a strange phenomenon in South Park, like a hidden cave with mysterious markings. Craig, being the curious and brave type, joins the reader in their investigation. Along the way, they have to rely on each other's skills - the reader's knowledge of ancient symbols (maybe they've been researching it for a school project) and Craig's ability to keep a cool head in spooky situations. This adventure brings them closer together as friends, and perhaps something more.
One plot idea could be that the reader is a hunter who has lost their faith, and Castiel helps them regain it. He shows them the good in the supernatural world and that not all angels or other beings are bad. Along the way, they form a deep bond based on mutual understanding and respect.
One idea could be that the OC is a new student at UA High School. She has a unique quirk that Shouto finds fascinating. They get paired up for a training exercise and gradually start to understand each other better. As they face challenges together, a bond forms between them.
One plot idea could be a story where the male reader is a new teacher at Fuyumi's school. They initially meet in a professional setting but gradually develop a deeper connection as they discover shared interests. For example, they both might be passionate about helping underprivileged students. Another idea is a scenario where the male reader saves Fuyumi from a dangerous situation, like a villain attack in the My Hero Academia universe. This event could be the starting point of their relationship, with Fuyumi being grateful and slowly falling for the male reader's brave and kind nature.
A possible plot could be that the male reader and Riven are part of a special training program. They start off as rivals, constantly competing with each other in various challenges. But as they face tougher opponents together, they gradually learn to respect and rely on each other. This could lead to a deep friendship and eventually a romantic relationship that is based on mutual understanding and shared goals.
One plot idea could be that the reader is a detective who is initially on Catwoman's trail. But as they interact more, they realize that Catwoman has her own code of ethics and they end up teaming up to take down a bigger bad in Gotham. It could be a story of mutual respect and understanding growing between them.
One idea could be a story where the reader is a new student at Dr. Stein's school. They initially find his eccentricities a bit off - putting but gradually come to understand his brilliant mind and form a friendship that could potentially turn into a deeper relationship over time. Another plot could involve the reader being a research assistant to Dr. Stein, and they work together to solve a mystery within the school or the scientific community.
Another plot could be that the reader is an alien diplomat sent to negotiate with Thanos. The reader tries to understand his motives for collecting the Infinity Stones from a different perspective and through their interactions, Thanos begins to question his own beliefs. This would be a great opportunity to explore his character in - depth and show a different side of him, while also developing a unique relationship between him and the reader that is based on diplomacy and mutual exploration of ideas.
