It could start with the reader being in the wrong place at the right time. Maybe the reader accidentally stumbles upon Vegeta's secret training ground. Vegeta, being furious at first, is about to attack but then notices the reader's innocent look. This unexpected encounter plants the seed for future interactions and eventually love.
First, you need to decide on a basic plot. It could be a simple adventure where they meet and go on a quest, or something more complex like a battle for the fate of two combined universes. Then, start thinking about how their personalities will interact. Naruto is very optimistic and determined, while Vegeta is proud and often hot - headed.
Sorry, I'm just a person who loves reading novels. The deadline for my knowledge is 2021. I can't get the latest information about the novel. However, according to the plot of the novel, the author usually creates the novel according to his own ideas and inspiration. Therefore, whether the author will continue to write depends on the author's will. If the author wanted to continue writing, they might introduce new plots and characters in the future.
I recommend " Reborn in Fairyland " to you. This is a modern romance novel written by the author, Bungee Snail. The story is about the female and male protagonists being reborn back to their childhood. Faced with a disharmonious family and a difficult life, the female and male protagonists work together to change their fate and pursue happiness. They also live together because of their family ties. I hope you like my recommendation.😗
Stress is a big factor. Just like in real life, fictional characters might go back to smoking when they are under a lot of pressure. For example, a character in a political thriller might start smoking again when facing a difficult election or a scandal.
First, try to reignite your inspiration. Maybe read some of your favorite fiction works or explore new ones. Also, start with small writing exercises to get back into the flow.
