Their relationship can be developed by having them face challenges together. For example, when dealing with the monster, they have to rely on each other's strengths. Gohan's power and Videl's intelligence can complement each other. They can also have heart - to - heart conversations during their battles or while preparing for them, which deepens their bond.
After getting married, they would support each other in their daily lives. Gohan might help Videl train even more, and Videl could encourage Gohan in his academic pursuits. They would also have to deal with family matters together, like taking care of Pan. Their relationship would grow deeper as they face challenges as a couple, such as balancing their personal goals with family responsibilities.
The relationship can be developed through trust. For example, when Gohan is in his Oozaru form, Videl can show that she trusts him not to harm her. This can be a start to a deeper connection.
One idea could be that they have a simple, traditional wedding but with a Dragon Ball twist. For example, all their Z - Fighter friends use their powers to create a unique and amazing wedding venue. Goku could accidentally almost destroy the wedding cake with a stray ki blast while showing off to Goten. Videl could wear a Saiyan - inspired wedding dress, with a red sash symbolizing the Saiyan heritage.
In some fanfictions, Gohan and Videl's relationship might be deepened. The 'lemon' aspect, if not in an inappropriate way, could symbolize something sweet and special between them. Maybe it represents a new phase in their relationship, like a honeymoon - like period full of love and new experiences.
One idea could be a fanfiction where Gohan and Videl's married life is filled with adventures in protecting the city. They could train their children together and pass on their skills. Another could be a story where they face challenges in their marriage due to Gohan's Saiyan heritage and Videl's human upbringing. For example, Gohan might have to deal with his occasional out - of - control Saiyan strength, and Videl has to learn to understand and support him during those times.
In this kind of fanfiction, Videl and Gohan might meet during a tournament. Videl, seeing Gohan's skills, is immediately drawn to him. She wants to learn from him and they start training together. This could lead to a lot of cute moments, like when Videl tries to copy Gohan's moves but fails comically at first, and Gohan patiently teaches her.
One great Gohan and Videl fanfiction is 'A New Adventure'. It shows them dealing with new threats in the Dragon Ball world after their marriage. It has a lot of sweet moments between the two.
