One idea could be a story where Chichi and Goten go on a training adventure together. They face various challenges and Goten learns important life lessons from his mother.
Perhaps a fanfic where Goten gets into some trouble at school and Chichi has to deal with it in her own unique way, while also showing her motherly love and wisdom.
A Goten and Harry Potter crossover could also be cool. Goten could be sent to Hogwarts by some magical accident. He would be the odd one out, not understanding the wizarding world at first. But his Saiyan strength could come in handy during the Triwizard Tournament, for example, when facing the dangerous tasks. Maybe he'd have to use his ki blasts instead of magic spells to get through certain challenges.
One idea could be a story where Gohan takes Chichi on a surprise trip to a peaceful, uninhabited planet for a second honeymoon. They could explore the unique flora and fauna there, and it could also be a chance for Gohan to show Chichi his newfound skills in survival and exploration, strengthening their bond.
Chichi is the main female character. She is often portrayed as a strict but caring mother. Goten, her son, is the focus as he grows and experiences things. Sometimes other characters like Gohan or Videl might make cameo appearances to add more depth to the story.
Perhaps there is a situation where they have to team up to protect the Earth from a new threat. In the process, they discover feelings for each other that they hadn't expected. Their relationship then develops against the backdrop of this high - stakes adventure.
One idea could be a story where Gohan takes Chichi on a surprise adventure to a new planet he discovered during his Saiyan studies. They could encounter new forms of life and have to work together to overcome challenges.
In the long run, they might realize that they need to change their behavior. They could start thinking about how to make it up to Chichi. Maybe they'll go and do some nice things for her, like getting her some flowers or cleaning the house really well without being asked. This would show that they've learned their lesson and are trying to be better sons.
Perhaps a fanfic where Chi - Chi discovers a lemon - themed cooking competition and she enters with Goku as her helper. They face various challenges related to using lemons in their dishes and in the process, their relationship deepens.
It could be that Gohan and Goten did something that seriously disappointed Chichi. For example, they might have broken an important family heirloom while playing their rough Saiyan games. This would definitely make Chichi angry enough to kick them out as a form of punishment.
One interesting storyline could be Goten getting into trouble at school and Chichi trying to discipline him in her own unique way. Maybe he used his Saiyan powers accidentally and she has to teach him about hiding his true nature among humans.
One possible storyline could be a heartwarming family adventure. Goten could go on a quest with Chichi to find a rare ingredient for a special family recipe. Along the way, they face challenges that strengthen their bond as mother and son.
