In the fanfic, Bulma's lack of forgiveness could drive a wedge between Vegeta and the rest of the Z - fighters as well. Since Bulma is an important part of their group, her feelings towards Vegeta might influence how others interact with him. This could create a lot of tension within the group and lead to different factions forming, with some siding with Bulma and others trying to convince her to forgive Vegeta.
There could be a lot of emotional turmoil. Bulma might start to resent Vegeta deeply. This could lead to her trying to find ways to get back at him, like using her intelligence to undermine his plans in the fanfic's plot. And Vegeta, on the other hand, might realize his mistake too late and struggle to regain her forgiveness.
Bulma might cut off all communication with Vegeta. She could focus solely on her own work and taking care of their child without Vegeta's presence. For instance, she might pour all her energy into her scientific research.
Maybe in the fanfic, Vegeta did something unforgivable like betraying Bulma's trust or putting her in great danger while under the influence of the Majin transformation. For example, if he endangered their family or made a pact with the enemy that directly opposed Bulma's values.
Well, it could be that Vegeta does something really unforgivable in the fanfic. Maybe he betrays Bulma in a very serious way, like getting involved with someone named Majon. It might lead to a lot of drama and heartbreak for Bulma, and she could be so angry that she decides not to forgive him no matter what he does to try and make it up to her.
The relationship in the 'Majin Vegeta x Bulma Fanfic' can be quite interesting. Majin Vegeta is a character with a new set of emotions and powers. Bulma, on the other hand, is a smart and strong - willed woman. The fanfic may depict how their relationship evolves in the face of challenges, like Vegeta's inner struggle with his new form and Bulma's attempts to understand him. It might also show how their love endures or changes during this unique situation.
One possible source of angst in such a fanfic could be the internal struggle of Majin Vegeta. He has this new, dark power that might put his relationship with Bulma at risk. For example, his altered state of mind due to the Majin influence could lead to him pushing Bulma away, fearing he'll harm her.
Maybe in the fanfic, Majin Boo has done something extremely unforgivable to Bulma, like harming her family or friends. This could be the reason for her inability to forgive.
One key theme could be redemption. Majin Vegeta is in a complex state, and the fanfic might explore his journey towards redemption through his relationship with Bulma. Another theme could be love's power. It can show how Bulma's love for Vegeta helps him in his struggle.
The plot could start with Majin Vegeta's pride getting in the way. He might feel that Bulma is disrespecting his new power as Majin Vegeta. So, he challenges her to a fight. Bulma initially panics but then decides to stand her ground. She uses her knowledge of Saiyan physiology (from all the time she's spent with Vegeta and the other Saiyans) to find his weak points. However, she also tries to reach out to the real Vegeta inside. As the fight progresses, Vegeta starts to see how strong - willed Bulma is and slowly begins to break free from the Majin influence.
One possible plot could be that Majin Boo has done something really bad that affects Bulma. But then, through a series of events, like Majin Boo saving Bulma's life or showing remorse in a very genuine way, Bulma begins to consider forgiveness. Maybe Majin Boo has to sacrifice something important to prove his change of heart, and in the end, Bulma fully forgives him.
I'm sorry, I haven't read a specific 'bulma wintt forgive majin boo fanfic' so I can't recommend one directly. You could try searching on fanfic websites like FanFiction.net or Archive of Our Own.
Perhaps when Bulma tries to get through to Vegeta but he snaps at her out of his newfound aggression. This is a really angsty moment as it shows the breakdown of their communication.
