@Ghostdevil ah i see what you mean. i think if the story did take itself seriously, it would have bothered to stress more consistent internal logic, like explaining the lack of guards, or going into the political aspect of the world. i'm kind of new to isekai, but so far the korean webtoons i've read only use the genre as a springboard for a comedy of situations, rather than dwelling on the details of this new and fantastical world. so i adjusted my expectations.
it IS confusing that a few chapters ago the MC kept getting thwarted, but now she's got everything incredibly under control... but i'm just treating it as a satire of crappy love stories at this point.
