Culinary adventures. Since they are both from the culinary world, many fanfictions will have them going on adventures related to food. Maybe they travel to different places to discover new ingredients for their restaurant in the fanfic, all while strengthening their relationship as a married couple.
There are also fanfictions that focus on cultural exploration through food. Since Soma has his own unique style influenced by his father and his upbringing, and Megumi has her traditional Japanese culinary background, writers might use this as a theme. They could show how the two characters learn from each other's cultures and incorporate different elements into their cooking, which in turn affects their relationship.
There's also 'The Married Life of Soma and Megumi'. It focuses on the more domestic side of their married life. How they decorate their home, deal with daily chores, and still find time to cook amazing dishes for each other. It shows a sweet and harmonious relationship where their love for food and each other blend seamlessly.
A prevalent theme could be the combination of their two different personalities in married life. Soma's more adventurous and experimental cooking style and Erina's refined and traditional approach. In the fanfictions, this might lead to interesting scenarios like creating new fusion dishes together as a married couple, or having friendly cooking competitions within the household to keep their relationship exciting.
Another theme is the exploration of their different personalities. Megumi is more reserved while Gojo is outgoing and flamboyant. Fanfictions often play with how these two personalities interact and complement each other.
A common theme is the development of their relationship. It often starts from rivalry in cooking and then evolves into something more like friendship or even a romantic relationship.
Often, they highlight their shared love for food. Since they are both in the culinary world in the original story, fanfics usually revolve around cooking challenges they face together or how they teach each other new techniques.
