One great fanfic idea could be a story where Yor and Loid have to go on a mission together outside of their normal family cover. Maybe they end up in a foreign city and have to rely on each other more than ever. This would deepen their relationship and also add some exciting action and adventure elements to the story.
By showing their shared experiences. For example, when they are both trying to protect Anya from something or someone. This common goal can bring them closer as they rely on each other's skills. They start to trust each other more and more with each passing situation.
Well, a simple fanfic could just be about Yor and Loid sharing a quiet moment at home. Just them talking about their day, and slowly realizing how much they've come to rely on each other. It's a sweet and simple concept that shows the growth of their relationship.
The potential for different storylines. The Spy x Family setting gives a lot of room for creativity. Fanfic writers can create all sorts of scenarios for Loid and Yor, from dangerous spy - assassin missions that test their relationship to simple, domestic moments that show their growing bond. There are also the added elements of Anya and the overall comical yet tense world they live in, which can be incorporated in unique ways in fanfics.
One idea could be that Yor and Loid have to go on a mission together where they have to pretend to be a couple in a more extreme situation than usual. For example, they are stuck on a deserted island and have to convince some dangerous smugglers that they are just honeymooners. This would force them to get closer and explore their feelings in a more intense way.
One great Spy x Family Loid x Yor fanfic is 'The Unspoken Bond'. It beautifully explores the relationship between Loid and Yor in a series of heart - warming and action - packed scenarios. It delves into how they gradually understand each other better while maintaining their secret identities.
Their relationship could develop further through shared experiences. For example, if they face a big threat together to their family or mission, it would force them to rely on each other more. Another way is if they start to open up about their pasts little by little. Maybe Yor shares more about her assassin training and Loid starts to tell her about some of his most dangerous spy missions.
One idea could be a mission where Loid and Yor have to pretend to be a couple at a high - society ball for a mission, but end up having a real emotional moment. Another could be a story where Yor's assassin past comes back to haunt her and Loid has to protect her and their family identity. Or perhaps a fanfic where they go on a family vacation and deal with the challenges of keeping their true selves hidden while still having fun as a family.
One common theme is the development of their relationship. Given their initial setup as a fake couple for a mission, many fanfics explore how they gradually come to truly care for each other.
