One common theme is redemption. Byakuya may have things in his past that he feels he needs to make up for in relation to Rukia. Another theme is family. Since they are related in the Soul Society context, the idea of family and how it affects their relationship is often explored.
One possible plot could be that rukia and byakuya accidentally end up taking care of a baby. They initially struggle as they are not used to this situation. Byakuya with his strict nature tries to impose order while rukia is more lenient. As they care for the baby together, they start to understand each other on a deeper level and their relationship grows stronger.
Yes, it can be quite popular. Many fans of the Bleach series are intrigued by the potential relationship between Rukia and Byakuya. Their complex dynamic in the original series gives a lot of room for fanfiction writers to explore different aspects of their relationship, from a deeper friendship to a romantic love. This allows fans to delve into scenarios that might not be fully explored in the official storyline.
One common theme is loyalty. Given their history in the original story, loyalty to each other, whether it's rukia's loyalty to byakuya as her superior or byakuya's loyalty to rukia as someone he cares about deeply, is often explored.
I also like 'The Unseen Connection'. It starts with a simple encounter between rukia and byakuya and then gradually unfolds their deep emotional bond. The story is well - paced and the characterizations are on point.
One common theme is loyalty. Byakuya is bound by his loyalty to the Soul Society and his family, and Rukia has her own sense of loyalty. Their relationship often has to navigate through these loyalties. For example, in many fanfics, Byakuya has to balance his duty to his family's name and his growing feelings for Rukia.
Rukia's kind and empathetic nature would make her very nurturing towards the baby. She would be quick to comfort the baby when it cries and would be very hands - on in its care. Byakuya, on the other hand, with his reserved and disciplined personality, might seem a bit cold at first. But his sense of duty would ensure that he provides for the baby's needs in a very organized and efficient way.
There are quite a few. 'The Unspoken Connection' is a great one. It delves into the unspoken understanding that exists between Byakuya and Rukia. It starts with small moments of them noticing things about each other that others don't. It also adds a bit of mystery to their relationship as the story unfolds, making it really engaging to read.
Another theme is redemption. For example, if there was a situation where Byakuya made a mistake regarding Rukia in the past, a fanfiction could be centered around his journey to make it up to her. This could involve him facing his own pride and learning to be more open with his feelings towards her.
One common theme is the exploration of their unspoken feelings. Since in the original series there's a certain tension between them, fanfictions often delve into what those feelings could be. Another theme is adventure, where they go on missions together and their relationship develops during those events.
