Well, it could be a story about Keith borrowing Lance's jacket by mistake. Then, Lance notices and is initially a bit annoyed but as they interact more because of the jacket situation, they start to understand each other better and become closer friends.
The fanfiction might be set in a situation where the team is on a mission. Keith gets injured and Lance gives him his jacket to keep warm. While wearing the jacket, Keith discovers a small token or note in the pocket that Lance had forgotten about. This discovery could lead to a series of events where Keith learns more about Lance's private side, and they bond over this new - found knowledge.
Maybe in the fanfiction, Keith is cold and without thinking grabs Lance's jacket. Lance sees Keith in it and realizes how good Keith looks in it. This could lead to some light - hearted banter between them and perhaps even a moment of realization for Lance about his feelings towards Keith, whether it's a deepening of their friendship or something more.
Obviously, Keith and Lance would be the main characters. They are the ones directly related to the concept of Keith wearing Lance's jacket. Other characters from their team or universe could also be included, like Shiro who might notice the jacket exchange and have some sort of reaction to it, or Pidge who could make some teasing comments.
In this fanfiction, perhaps Keith would be really nervous at first. He might worry about making a good impression on Lance's family. Maybe he'd bring a small but meaningful gift, like a flower from his home planet.
He might be polite but a bit guarded at first.
One common theme is friendship. Their relationship often starts as a rivalry but gradually turns into a deep friendship in many fanfictions. For example, in stories like 'From Rivals to Allies', their journey of understanding and supporting each other is the central focus.
Teamwork is also a big theme. In many fanfictions, they have to work together as part of a team and their relationship is strengthened through that. And there's the theme of sacrifice, where they might be willing to sacrifice for each other.
In this fanfiction, Keith might initially feel out of place when meeting Lance's family. He could be a bit shy or reserved at first.
Well, it could symbolize their closeness. In many fanfics, when a character wears another's clothing, it shows a special bond. Maybe it represents protection, like Percy's jacket is a way for him to be there for Annabeth even when he's not physically around.
One common theme is friendship. Many fanfictions explore how Lance and Keith's friendship evolves over time. For example, they might start off as rivals but gradually become close friends who rely on each other.
A lot of the fanfictions about their kiss also explore the reactions of the other characters in the Voltron team. Some might be supportive, while others could be initially shocked or confused. The kiss can also be a symbol of a new era in the team's dynamics, as Keith and Lance's relationship changes. It can lead to interesting storylines about how the team adapts to this new development.
The 'hurt/comfort' theme is also common. This could be where one of them gets injured or is in an emotional distress and the other is there to comfort and support, which then deepens their relationship. For example, if Lance gets hurt during a battle and Keith takes care of him. It's a great way to show their growing bond.
