In this fanfiction, perhaps Bell Cranel is neglected by Hestia when it comes to getting proper equipment or resources. Hestia might be allocating the familia's funds to other areas, thinking they are more important. So Bell has to take on low - paying quests just to earn enough to buy basic gear. This could lead to him facing more dangerous situations than he should, and also cause a rift between him and Hestia as he feels she doesn't value his safety and growth.
It could be another god who sees Bell's potential and wants to use his situation of being neglected by Hestia to their advantage. This god might try to lure Bell away from Hestia's familia by offering false promises of better treatment and more opportunities.
Their relationship can be developed through shared experiences. For example, if they go through a dangerous dungeon together, Bell can protect Hestia and she can in turn use her divine powers to support him. This mutual reliance will strengthen their bond.
Well, a plot might involve Bell getting injured in a dungeon and Hestia having to use all her powers to heal him. During this time, they have deep conversations and realize new things about each other. Or perhaps there's a story where Bell has to compete in a special tournament, and Hestia is his only supporter. They train together and their relationship takes on a new dimension. Also, a plot could be that a mysterious force tries to separate them and they have to fight against all odds to stay together.
It could be a character from a rival group. They see Bell Cranel as a threat to their plans and so they betray him by setting him up in a dangerous situation.
