One possible theme could be female friendship. Through the girls' conversations in the story, it might show how they support, confide in, and understand each other on various levels.
Frieza might initially be shocked. He's used to being a feared and powerful being, and the idea of having a family is very foreign to him. So he could be in denial at first.
"Reborn in the Apocalypse, It's Time for the System to Fight Monsters" was a sci-fi novel about the crisis of the apocalypse. It was about the female protagonist's rebirth before the apocalypse, but she realized that she was supposed to cultivate and fight monsters instead of working in the apocalypse. Thus, she embarked on a wonderful adventure. This novel was a pseudo-infinite-style game novel. The plot was compact and the writing was beautiful. It was suitable for readers who liked games. I hope you like my recommendation. Muah ~
For Yamcha, you can focus on his growth from being a bit of a comical character to a more serious and respected fighter in the context of his relationship with Frieza. Maybe he learns from Frieza's cold and calculating nature how to better strategize in battles. For Frieza, his development could be about him learning to care for someone other than himself. He could start to see Yamcha as an equal, which is a huge shift from his usual superiority complex.
In the manga, Frieza is presented as a tyrant with immense power and a cruel streak. His character development is complex, evolving as the story progresses. His actions often drive the plot and create intense conflicts.
Then, introduce some shared experiences. Maybe they get trapped in a strange dimension together. In this new and dangerous place, they have to rely on each other's strengths. Goku's physical power and Frieza's cunning could be the keys to their survival. As they go through these experiences, they start to see each other in a new light and their relationship begins to change.
'Cemetery Boys' could also be considered. It has elements of the supernatural and a strong focus on character development. The relationship dynamics in the story can give new F F romance readers an idea of how to build a great love story. You can get it on Amazon. Another good one is 'Red, White & Royal Blue' which shows a relationship that overcomes differences. It can inspire those new to F F romances in terms of how to handle relationship challenges.
The theme of female friendship in the story is highly relevant to modern society. Just like in the story, women today rely on their friends for emotional support, advice, and a sense of community. Social media has also expanded the scope of these friendships, allowing girls to connect more widely.
