I really like 'Yu and Yosuke: Unbreakable Ties'. It focuses on how their relationship evolves over time, especially after dealing with all the strange events in the game. It has some really heart - warming moments. A different fanfic, 'Side by Side', shows them in their daily lives, just hanging out and having conversations that reveal more about their characters and how they support one another.
Show their relationship evolving over time. At the beginning, Yosuke might be a bit of a flirt in a light - hearted way towards the reader. But as they get to know each other better, he becomes more sincere. The reader, on the other hand, could start off being a bit reserved but gradually open up to Yosuke. You can also include some misunderstandings along the way, like Yosuke thinking the reader likes someone else. Working through these misunderstandings can make their relationship more complex and interesting.
His friends would probably take care of him. Midoriya would be very eager to help, using his kind-hearted nature. He would make sure Todoroki is fed and comfortable.
In such a fanfic, the author may take creative liberties. For example, they could delve deeper into the emotional bond between Souji and Yosuke. It might depict moments of trust - building, like when they face tough Shadows together. Also, the fanfic could show how their different personalities complement each other, with Souji's calmness and Yosuke's more energetic nature.
One idea could be that all his friends at UA plan a surprise birthday party for him. They decorate the common room with his favorite colors, blue and red. Another plot could be Todoroki spending his birthday with his family, trying to reconcile with his father on this special day. Maybe he receives a heartfelt gift from his mother that has a deep emotional significance.
