It could also be a symbol of a new power - up. In the Dragon Ball series, new physical changes often lead to increased power. So, getting his tail back might mean that Goku is about to reach a new level of strength. Maybe he'll be able to transform into a new form that is related to his Saiyan heritage and the presence of the tail. This could give him an edge in future battles against stronger opponents.

Another storyline could involve Supreme Kai of Time getting into trouble in a different timeline and Goku having to rescue her. Along the way, they discover new forms of power and new allies.
There's a fanfiction where Goku accidentally ends up in West Kai's realm in a rather comical way. This sets off a series of events that lead to them getting closer. It's filled with action and light - hearted moments, showing Goku's naivete and West Kai's patience.

In some fanfictions, Goku shows his love by being proud of Chichi. He may brag about her cooking skills to his friends or simply admire her strength in handling the family and household. This simple act of admiration can be a way of showing his love in their married life.
