Develop the reader's backstory. If the reader has moved around a lot because of their parents' jobs, it can create a sense of longing for a stable relationship like the one they might develop with Shindou Takuto. This backstory can also be used to explain why they might be hesitant or eager in different situations in the fanfiction. Their past experiences shape their reactions to things in the present story.
One idea could be a story where the reader is a new student at Shindou Takuto's school. They accidentally bump into him in the hallway, and from that moment, he becomes intrigued by the reader. As they start to interact more, they discover they have a shared love for a particular sport or hobby, which brings them closer together.
Some fanfictions explore the theme of loyalty. They might face situations where they have to choose between each other and something else, like a different team or a personal ambition. And the way they handle that, staying loyal or having to work through a moment of doubt, is a common plotline. Also, the theme of discovery, like finding out new things about each other that they didn't know before, can be quite prevalent in these fanfictions.
