@cgr 20 chapters is usually long enough to get a feel for the story, even though some of the pages are small. Already there are what, 5 characters other than the protagonist who show up more than once? And they're all female. It doesn't have the feeling of a harem story so far but for a non-harem story with a male main character, the female:male ratio is high. Just an observation, and maybe the comic will be different (doubt it's much different based on the cover).
Not saying I can tell how it will work out in the future for sure but I get the feeling the author wants to focus on building a company that earns money by grinding rare drops in the dungeons so even any romance with the female character who shows up the most should be really slow.
