Another possibility is that 'him' could be a new character introduced in the fanfic. This new character could have some kind of relationship with Bulma that goes wrong. For example, he lies to her about his identity or his intentions, and as a result, Bulma pushes him away.
Maybe 'him' is Goku. There could be a situation where Bulma feels that Goku's constant battles are endangering the people around him, including her and her family. So, she tries to push him away to stop him from getting into more dangerous fights. Or perhaps she has some unrequited feelings for Goku that she's trying to suppress by pushing him away.
Well, it could be about a complex relationship where 'bulma' has some reason to push 'him' away. Maybe she discovers a secret about 'him' that makes her feel betrayed or scared. For example, if 'him' is involved with some dangerous group without her knowledge.
First, really understand the world and characters of Spirited Away. Re - watch the movie, study the personalities of Chihiro, Haku, and the other spirits. Then, come up with an original idea.

It gives a whole new perspective on his character and his actions throughout the Spirited Away story. It's a must - read for any Spirited Away fan who wants to know more about Haku.
Well, without actually reading it, it's hard to say exactly. But generally, an 'Avengers fanfic' might be about the Avengers characters in a scenario that's different from the official Marvel storylines. It could involve the heroes going on a new adventure, facing a new villain, or having different relationships with each other. Maybe in this 'a world away' one, they are in a parallel universe or a far - off place that changes the whole dynamic of their usual superhero activities.
I'm not entirely sure as I haven't read that specific fanfic. But it might be about Naruto being sealed away in some way, perhaps in a different scenario from the original story. Maybe some new villain or power manages to seal him.
One common theme is self - discovery. The characters often go through a journey of finding out more about themselves during their week away at the camp.
One common theme is loyalty. Fans in these fanfics often show extreme loyalty to their home team, even during tough away games. Another theme is the difference in the environment between home and away games. This can include the stadium facilities, the crowd behavior, etc.
A 'locked away pokemon fanfic' could be about Pokemon that are locked away for various reasons. Maybe it's about rare or dangerous Pokemon that are locked in a secret facility to protect the world from them. Or perhaps it's about Pokemon that are unjustly imprisoned by villains and the story follows a hero's journey to free them.
It offers a fresh take on the Avengers universe. The story might introduce new plotlines or character developments that fans find exciting.
It's hard to say without reading the specific fanfic. But it could be a young and brave trainer who stumbles upon the locked away Pokemon. There might also be a villain or a group of villains who are responsible for locking the Pokemon away in the first place.
