One possible story could be where Vegeta accidentally says something really hurtful during an argument about his training obsession, making Bulma feel neglected. Another could involve Vegeta's Saiyan pride causing him to make a decision that directly impacts Bulma negatively, like leaving for a dangerous mission without considering her feelings.
In some fanfictions, Vegeta might get influenced by his past traumas and take it out on Bulma. For example, he could be haunted by his experiences with Frieza and in a moment of anger, push Bulma away verbally. Or perhaps he becomes too focused on surpassing Goku and in the process, forgets to be a good partner to Bulma, causing emotional pain.
One interesting story could be about their adventures together in a parallel universe. In this fanfic, Vegeta and Bulma might face new enemies that they have to defeat while also dealing with their relationship issues. Maybe they discover a new power that only their combined efforts can control.
Another reaction could be that Bulma tries to communicate with Vegeta. She would sit him down and try to talk about how his actions are making her feel. However, if Vegeta is unresponsive or dismissive, it would only add to her heartbreak.
One interesting aspect could be the exploration of Vegeta's softer side. In fanfiction, his kiss with Bulma might be a moment where he lets down his tough exterior and shows his deep affection for her. It could also involve the development of their relationship further, like how they deal with the challenges of being from different species while in love.
Some exist because it adds drama to the relationship. Writers like to explore the complex emotions and conflicts that can arise between two very different characters like Vegeta and Bulma.
In Vegeta and Bulma fanfiction, a great part is seeing how their different personalities mesh. Vegeta is all about power and pride, while Bulma is intelligent and resourceful. Fanfictions might show how they balance each other out. For instance, Bulma could use her smarts to come up with strategies in battles that Vegeta is involved in. Also, their cultural differences, Vegeta being from a Saiyan culture and Bulma from Earth, can lead to interesting storylines. Writers can explore how they deal with these differences and grow closer because of them.
One interesting fanfiction could be about Vegeta's struggle to adapt to family life with Bulma while still being a Saiyan warrior. Maybe he tries to teach Trunks Saiyan traditions in a world that's mostly human.
One possible scenario could be that Vegeta is too focused on his training and ignores Bulma's emotional needs. He might be constantly pushing himself to get stronger and in the process, not give Bulma the attention she desires. For example, he could skip out on family events or important dates just to train.
Some fanfics explore the idea of Vegeta and Bulma raising their family. They might face challenges from outside forces while trying to protect their family, which makes for an exciting read.
One interesting aspect is the contrast between Vegeta's tough Saiyan nature and Bulma's more earthly and emotional human side. Their love often shows how two very different personalities can come together. For example, Vegeta's initial pride and aloofness gradually gives way to a deeper emotional connection with Bulma. This transformation is a key part of their relationship in fanfiction.
A possible plot could also revolve around a threat to the Earth where Vegeta and Bulma's relationship is put to the test. Vegeta has to go and fight, and Bulma has to deal with the fear of losing him. This could show the depth of their bond and how they support each other through tough times.
