One idea could be that Goku forgets their anniversary. Chi Chi is initially angry but then decides to use this one - week period to remind Goku of their relationship. She sets up various challenges and tasks for Goku related to their past memories together. As Goku goes through these, he rediscovers his love for Chi Chi in a deeper way.
A possible plot for the fanfic could be that a strange energy source appears near their home. Goku and Chi Chi have one week to figure out what it is before it causes chaos. During this time, Chi Chi shows her own strength and intelligence, helping Goku in ways he didn't expect. They work together as a team, and their bond grows stronger as they face this new threat.
Well, in a one - week fanfic about Chi Chi and Goku, they might go on a training adventure together. Chi Chi could be trying to keep up with Goku's intense training regime, and there could be some cute and funny moments as she struggles. Maybe they also take some time to just relax and have a family picnic with Gohan. It would be a story full of action, family love, and the unique dynamic between these two Dragon Ball characters.
I'm not sure if there is an actual fanfic with that exact plot. Fanfic topics can vary widely, but this seems like a rather unfaithful and out - of - character concept considering Chi Chi's strong bond with Goku in the original series.
Love and family are very common themes. Their relationship as husband and wife, and as parents to Gohan and other children is often explored.
Power struggles can also be a common theme. Dark Goku is often depicted as very powerful. Chi - Chi, on the other hand, has her own strength in terms of her determination and will. The power dynamic between them can create interesting scenarios in the fanfic. There could be moments where Chi - Chi has to find ways to stand up to Dark Goku, or Dark Goku might try to use his power to manipulate or control her in some way.
Love and family are very common themes. Since they are a married couple and have a son, many fanfics explore how they navigate their relationship while also raising Gohan. For example, in some fanfics, Goku tries to be a better husband and father by spending more time at home.
One possible plot could be that Bulma might be jealous of the relationship Goku and Chi - Chi have. Maybe she sees how much Goku has changed since being with Chi - Chi and she misses the old, carefree Goku. So, she tries to create misunderstandings between them by, for example, making it seem like Goku is more interested in training with her than spending time with Chi - Chi.
One positive idea could be a fanfic about Goku and Chi - Chi going on a family adventure with Gohan. It could focus on how they work together as a family, teach Gohan about their Saiyan heritage, and face challenges as a family unit.
Maybe in this fanfiction, Goku realizes that he and Chi - Chi have very different personalities. Chi - Chi is often more concerned with family and a stable life, while Goku is a free - spirited adventurer. This clash of values could lead him to decide not to marry her. For example, Chi - Chi may want Goku to stay at home and help raise Gohan, but Goku is eager to explore new planets and fight powerful enemies.
One popular Goku and Chi - Chi fanfic is 'A Day in the Life of the Son Family'. It shows their daily interactions in a really heartwarming way.
In a fanfiction like this, perhaps Bardock is on a mission in the afterlife and it leads him to cross paths with Goku and Chi - Chi. Bardock could test Chi - Chi's strength and worthiness to be with his son. Chi - Chi would rise to the challenge, showing her determination. Goku would be in the middle, trying to make sure his father respects his wife. And in the end, Bardock could give his blessing to their relationship, seeing how happy they are together and how Chi - Chi has made Goku a better person in many ways.
