Usually, I don't drop stories by the 5th chapter unless they're too frustrating or make no sense... I'm thinking of dropping this out of a mixture of boredom and disinterest in the MC, she is too bland and I don't mean her looks (well that too but it's not the reason), she is just hella boring and has 0 personality. The author is probably going for the "relatable" character thing but I don't read isekai to see someone like 99% of the people. If I wanted that I'd read a slice of life genre or some realistic shit. If I read isekai I want novelty in the setting and also a refreshing MC. I'm not expecting every isekai to have a badass MC with awesome martial arts but the MC needs to be special in some shape or form.
As I said I'm "thinking of dropping this" and haven't 100% made my decision so I might stop reading this until it has 20-30 more chapters and then read them altogether and see if the MC, pace and setting change or not
