In high school fanfiction, their relationship could develop through shared extracurricular activities. Let's say they both join the school's gardening club. At first, they are constantly at odds, with Shizuo accidentally uprooting plants Izaya has carefully tended. But over time, as they work on a big project like creating a school garden for a competition, they start to see each other's strengths. Shizuo's physical strength is useful for moving heavy objects, and Izaya's creativity is great for designing the layout. They gradually become friends, or at least friendly rivals. Another way could be through a mutual friend. A classmate who is friends with both of them gets them to hang out together outside of school, and they find common ground in their dislike for the school bully.
One way to develop their relationship in high school fanfiction is through academic competition. They could be the top two students in their class, always vying for the highest grade. Shizuo is good at math and science, while Izaya excels in literature and history. At first, they are bitter rivals, but when they are paired up for a group project that combines all these subjects, they are forced to cooperate. During this process, they realize that they can learn a lot from each other. For instance, Shizuo learns how to analyze texts better from Izaya, and Izaya gains a better understanding of scientific concepts from Shizuo. This mutual learning experience could lead to a more complex relationship, from pure rivalry to a begrudging respect and eventually, perhaps, friendship.
