Well, it depends on the specific fanfiction. There are a vast number of RWBY fanfictions out there. Some authors might choose to have Blake and Sun share a kiss as a way to develop their relationship further, perhaps exploring their feelings in a more in - depth way than the original series allows. While in other fanfictions, their relationship might take a different turn and a kiss may not occur.
One common theme is friendship. Blake and Sun have a unique bond, and many fanfictions explore how they support and understand each other as friends. For example, in some stories, they help each other through difficult times at Beacon Academy.
There's also a fanfiction called 'Blake and Sun: A New Bond'. This one delves deeper into their relationship, exploring how they support each other in the face of danger. It has some really cool action scenes and heartfelt conversations between the two characters. The author does a great job of capturing their personalities.
Obviously, Blake and Sun are main characters. Blake, with her complex past as a Faunus and her relationship with the White Fang. Sun, who is always so energetic and friendly. And then there are members of Sun's family. They could include his parents, siblings if he has any. These family members play important roles in shaping the story, whether it's providing support, causing conflict, or teaching valuable lessons to Blake and Sun.
One interesting plotline could be Sun's family welcoming Blake into their family. Maybe they have some traditional family activities that Blake has to get used to, like a special family gathering where they share stories of their past adventures. It could also involve Sun's family helping Blake deal with her own family issues or past traumas.
Overcoming differences is also a frequent theme. Blake is a Faunus and has her own set of experiences and insecurities, while Sun is a carefree monkey - Faunus. Fanfics often explore how they deal with their differences and grow closer as a result.
One interesting RWBY Sun and Blake fanfiction could be 'Sun's Adventure with Blake'. In this fic, they might go on a journey through the dangerous Grimm - infested areas, facing challenges together and growing closer as friends or perhaps more. Another could be 'Blake and Sun's Hidden Past' which delves into their backstories and how they might have unknowingly been connected before they met at Beacon. There are also fics that focus on their teamwork during battles, like 'Sun and Blake: Battle Partners', showing how their unique skills complement each other in combat situations.
A less common but still present theme is redemption. If one of the characters makes a mistake or has a troubled past, the other can be a part of their journey towards redemption. For example, if Blake has some unresolved issues from her past with the White Fang, Sun could be there to support her and help her find a path to make things right. This adds depth to their relationship and the story as a whole.
One possible scenario could be after they have a big adventure together and they realize their deep feelings for each other. Another could be when Sun saves Blake from a dangerous situation and in the heat of the moment, they kiss.
One common theme is friendship. Their relationship often starts as a strong friendship in these fanfics. For example, they might support each other in battles or during difficult times at school.
