Hestia and Bell do not get together in the light novel series “Is It Wrong to Try to Pick Up Girls in a Dungeon?” Hestia has feelings for Bell and it is clear that she cares deeply for him, but Bell only sees her as a goddess and not as a romantic partner.
In Volume 8 of the light novel series, there is a scene where Hestia confesses her feelings to Bell. She tells him that she loves him and wants to be with him. However, Bell does not reciprocate her feelings in a romantic way. He acknowledges her feelings and thanks her for everything she has done for him, but he does not see her as anything more than a goddess.
It is clear throughout the series that Bell holds Hestia in high regard and respects her as a goddess. He is grateful for her support and guidance, but he does not have romantic feelings for her. He sees her more as a mentor and friend rather than a potential romantic partner.
This dynamic between Hestia and Bell is a central aspect of their relationship throughout the series. While Hestia may have romantic feelings for Bell, he does not feel the same way. Their relationship remains platonic, with Hestia continuing to support and care for Bell as his goddess.
It is important to note that this is based on the light novel series and may differ from the anime or other adaptations of the story. However, in the light novels, there is no indication that Hestia and Bell will get together romantically. Their relationship remains one of friendship and mentorship.
