A possible secret could be that they both have a shared dream for their family that they haven't told anyone else yet. They might be planning a future for their son Trunks in a very specific way, like sending him to a particular school in the future. This is a secret they keep between them as they don't want others to interfere or know their long - term plans for their family.
One little secret could be the way Vegeta slowly warms up to Bulma's family. At first, he seems so aloof, but over time, he starts to care about them in his own way.
Sure. One interesting secret could be that Bulma has a collection of mementos from their early days together, like a small piece of cloth from Vegeta's Saiyan armor when he first came to Earth. Vegeta doesn't know about this collection, and it's a sweet secret that shows Bulma's sentimental side.
In the fanfiction, their relationship is full of passion. It's not just a physical passion but also an emotional one. Vegeta, who was once a cold - hearted Saiyan, has softened because of Bulma. He shows his love in his own way, like training hard to protect her. Bulma, in turn, is attracted to Vegeta's strength and his gradual transformation into a more caring person. They bicker sometimes, like any couple, but it's all part of their unique dynamic.
In such fanfiction, Vegeta might make Bulma happy by showing his softer side. Maybe he cooks a special meal for her. Vegeta is often portrayed as tough, but when he does something out of his usual character like cooking, it can be a sweet surprise for Bulma.
Vegeta would likely still be his proud and strong - willed self, but with a newfound tenderness towards Bulma. He might be a bit more protective and less quick to anger. Bulma, on the other hand, would be her intelligent and sassy self, always ready to challenge Vegeta in a playful way.
One challenge could be protecting the baby from their enemies. Vegeta has made many foes over the years, and they might target the baby. Also, Vegeta's Saiyan nature might make him push the baby too hard in training, while Bulma wants a more relaxed approach. This difference in parenting styles could cause some friction between them.
The fact that they have a family together also has some secrets. For instance, how they decided on the names for their children. There could be hidden meanings or stories behind those names that are like little secrets. Also, their family life is a blend of Saiyan and Earthling cultures, and the little ways in which they navigate those differences and make it work might be considered as secrets of their relationship. For example, how they handle Trunks' Saiyan powers while also making sure he has a normal Earthling upbringing.
In DBZ Vegeta and Bulma fanfiction, there can be alternate universes explored. Maybe in one universe, they meet under different circumstances. For instance, instead of Vegeta coming to Earth as an enemy, he could be an ally from the start. This would completely change the dynamics of their relationship. It could lead to a more romantic and less combative start to their relationship, and the fanfiction could explore how this different beginning affects their future together.
In the fanfiction, their relationship could be explored by showing how they adapt to each other. Vegeta's feral side might require Bulma to be more patient and understanding. And Bulma's needs might force Vegeta to become more domesticated in some ways. For instance, he might have to learn to control his temper around her family and friends. It could also show how their relationship evolves over time, starting from initial attraction despite their differences to a deep, loving bond that endures through various challenges.
Their relationship would likely become more intimate and committed. With a baby on the way, Vegeta would probably be more protective of Bulma. He might show his love in more practical ways, like making sure she has everything she needs.
