Another theme could be the exploration of their different personalities. Ruby is often portrayed as more carefree and enthusiastic, while Weiss is more reserved and proper. When they kiss, it's sometimes a moment of breaking down those barriers and the fanfiction may focus on how their personalities complement each other during and after that moment.
Some fanfictions have the theme of a secret relationship. They might be hiding their feelings from the rest of the team for various reasons, like not wanting to disrupt the team dynamic or being afraid of how others will react. The kiss then becomes a significant moment in this secret relationship, full of tension and anticipation.
One common theme is the development of their relationship from initial animosity or indifference. In many fanfictions, they start off not getting along well in the team, and then as they go through various challenges together, their feelings change and lead to the kiss. It shows how they grow closer over time.
One common theme is the overcoming of differences. Ruby and Weiss start off with a somewhat rocky relationship in the show, so in fanfics, their kiss might symbolize them getting past those initial disagreements. Another theme could be the discovery of new feelings during a time of crisis. For example, they might be in a battle together and realize their love for each other in that intense moment.
A prevalent theme is the exploration of their relationship. This can range from a deep platonic bond to something more romantic in some fanfictions. Also, the theme of loyalty is common. They are loyal to each other as members of their team, and fanfictions will often have situations where this loyalty is tested, like when one of them is in danger and the other has to make a choice to save them.
A common theme is the overcoming of differences. Ruby and Weiss start off with some friction in the show, so in fanfiction, it's often about how they get past those initial issues and fall in love. Another theme is the support they give each other during battles and tough times.
A theme that sometimes shows up is the idea of redemption or self - discovery. Maybe Ruby has some past mistakes or Weiss has some insecurities she needs to overcome. Through their relationship, they are able to find themselves and become better versions of themselves. This can add a lot of depth to the fanfiction and make the characters more relatable to the readers.
Power dynamics also play a big role. Weiss, as a vampire, may have certain powers and abilities that Ruby doesn't. This can lead to situations where Ruby is in a more vulnerable position, or where Weiss has to protect Ruby from other threats. And also, the idea of Ruby trying to understand and accept Weiss' vampiric nature is often explored. For example, how Ruby deals with Weiss' need for blood or her different lifestyle. This exploration of acceptance and difference is a very common theme in such fanfictions.
A common theme is friendship development. Since they start as just teammates, a lot of fanfictions explore how they become closer friends. For example, they might share secrets or have deep conversations that bring them closer.
One common theme is the 'opposites attract' concept. Ruby's carefree and optimistic nature is a contrast to Weiss's more serious and often prickly exterior. Another theme is growth. As they develop feelings for each other, they also grow as individuals. For example, Ruby might become more confident in her leadership while Weiss becomes more open - minded.
Another theme is growth. Both Ruby and Weiss are on their own paths of development, and in fanfics, their relationship can play a part in that. They might learn from each other's strengths and weaknesses, like Weiss teaching Ruby about discipline and Ruby teaching Weiss about having more fun.
Love and its discovery is also a frequent theme. As they spend more time together, the fanfics often explore how they gradually realize their feelings for one another. It could be through small moments like sharing a meal or a big event like saving each other's lives, which then leads to a deeper emotional connection between Ruby and Weiss.
Love and romance can also be a theme, although not always in a traditional sense. It might be more about the deep emotional connections between them. Some fanfictions might explore a more complex relationship where their feelings for each other are a mix of friendship, admiration and something deeper. For instance, Ruby might look up to Winter as a role model and at the same time have a special bond with Weiss, and these relationships can be explored in different ways in fanfiction.
