Sure. Many fanfic writers like to delve into the relationships between characters. Chi Chi and Bulma have a long history in the Dragon Ball universe. A fanfic about their friendship might show how they support each other, deal with the crazy adventures their male counterparts get into, and bond over their own unique strengths and weaknesses. For example, Chi Chi's strong - willed nature and Bulma's intelligence could make for a great combination in a story about their friendship.
Honestly, I haven't come across a fanfic that specifically features Bulma, this 'have him' idea, Chi - Chi and Vegito in a great way that I could recommend. However, when exploring fanfic sites, pay attention to the tags. If a fanfic is tagged with all or most of these characters, it's more likely to be relevant. Also, look for writers who are known for their well - written Dragon Ball fanfics. Sometimes they might not have exactly what you're looking for, but their writing style could still be enjoyable and they might create something similar in the future.
One possible plot could be that Bulma might be jealous of the relationship Goku and Chi - Chi have. Maybe she sees how much Goku has changed since being with Chi - Chi and she misses the old, carefree Goku. So, she tries to create misunderstandings between them by, for example, making it seem like Goku is more interested in training with her than spending time with Chi - Chi.
Chi - Chi would likely be very hurt at first. But then she would get angry and start thinking of ways to prove to Goku that their relationship is strong. She might cook his favorite meals and remind him of all the good times they've had together, while also giving Bulma a piece of her mind.

A mentorship relationship could be explored. Bulma, with her knowledge of technology and the world outside of martial arts, could mentor Chi Chi in certain areas. For example, teaching her about new inventions or different cultures. Chi Chi, in turn, could teach Bulma about discipline and family values.
Goku would probably be really confused. He loves Chi - Chi and their family, and he might not understand why Bulma would want to break them up. He might just tell Bulma straight that he's happy with his life as it is. Chi - Chi, on the other hand, would be furious. She's very protective of her family and her relationship with Goku, and she'd likely give Bulma a piece of her mind.
Well, 'chi chi dies fanfic' could potentially be a work of fan fiction centered around the death of a character named Chi Chi. Maybe it's part of a story arc where the writer wanted to explore the impact of Chi Chi's death on other characters in the fictional universe. It could also be a rather dark take on the original story that the character belongs to, perhaps aiming to evoke strong emotions in the readers who are familiar with the source material.
I'm not sure if there is an actual fanfic with that exact plot. Fanfic topics can vary widely, but this seems like a rather unfaithful and out - of - character concept considering Chi Chi's strong bond with Goku in the original series.
