I'm not entirely sure as it's a fanfiction, but typically there might be a young and idealistic character who is new to the loid house. This character could bring a fresh perspective and energy.
One possible interesting plot could be a misunderstanding between the characters in the loid house. For example, a character might misinterpret another's friendly gesture as something more romantic, leading to a series of comical and heart - warming events as they figure things out.
In fanfiction, the idea of Loid and Yor having a pregnancy can be really interesting. It often adds a new layer of depth to their relationship. Writers might explore how they handle the news, their concerns about raising a child in their complex situation, and how it could potentially change their dynamic as a couple.
There's a fanfic titled 'Loid and Yor's First Real Date'. In this one, the author explores what would happen if Loid and Yor actually went on a date without the mission - related pressure. It delves into their feelings for each other in a more personal and romantic way. It has some really sweet moments that will make you smile.
Another good one is 'The Spy and the Assassin's New Adventure'. In this, Yor and Loid find themselves in a new and unexpected situation. It's exciting because it takes their relationship to a different level while still maintaining the charm of their characters. It has a lot of action and some really cute moments between them too.
