Often, Kid Goku is portrayed as the carefree and adventurous type. He's always looking for the next exciting thing to do, whether it's chasing after a strange animal or exploring a new area. He might be a bit naive in some aspects, especially when it comes to things like emotions.
One popular storyline could be their adventures together in the mountains. They might encounter strange creatures and have to use their wits and skills to overcome difficulties. For example, they could find a lost magical item and have to return it to its rightful place.
In the fanfiction, perhaps Kid Goku is on a journey to find stronger opponents to train with. He comes across Gine who is in a difficult situation, like being chased by some bad guys. Goku jumps in to save her. After that, Gine is so grateful that she decides to cook for Goku. As they sit down to eat, they start to exchange their life experiences. Goku is amazed by Gine's gentle nature, and Gine is impressed by Goku's courage and strength.
The two main characters are Kid Goku, the young and energetic Saiyan, and Gine, who is an important figure in the Saiyan world. Kid Goku is known for his love of fighting and his pure heart. Gine, on the other hand, has her own story and personality. In this fanfiction, their encounter will surely bring out different aspects of their characters as they interact with each other.
Well, the plot could involve Naruto coming across a powerful being from the Dragon Ball universe who decides to teach him the Kamehameha. Naruto, being the eager learner he is, starts practicing it.

He could then use this new skill in a big battle against a common enemy, surprising his friends and foes alike.
Well, Vegeta would be a likely character. He might be initially suspicious of the female Goku. Maybe he thinks she's a threat or just can't believe there's another Goku - like being. He could be there to add some comical moments as he tries to understand the situation.
Perhaps a powerful villain has the ability to combine different powers from different universes. This villain targets Naruto and in the process of fighting against this threat, Naruto somehow absorbs the knowledge of the Kamehameha. He then has to figure out how to use it in his own ninja - style way.
