I don't understand why this series has become so popular. It has the same problems (rather just one "problem") as a lot of other mediocre harem titles; Girls just inexplicably like the MC.
Like, I can get why we'd follow this guy due to him having the special skill allowing him to level up extremely quickly, but why do all these girls suddenly wet their panties when they first so much as glance at him? The only one who has any real understandable reason to would be Lili, because he saved her from the life she hated. But Hestia, the pub girl (3 of them, in fact), Freija and Valen-whatsherface all just suddenly become infatuated with him and do nothing but think about him practically 24/7. Puh-leaaase.
Not to mention a lot of things which don't make much sense at all; why aren't there other members in the Hestia familia? Like, I get why in the beginning (just starting out n all) but after Bell gets all popular n shit, I'd imagine loads of people would be lining up to join Familia Hestia. And the whole levelling up system doesn't make much sense either, like, which entity decides the amount of experience points and what constitute as being worthy of being given experience. Why do they only get them after getting a back tattoo from their god and not at the moment of doing the deed worthy of experience, etc? I really could go on.
