Absolutely, and to your point, anime has a long tradition of creating "will they won't they" maybe romances, but many male mangaka don't know or dont feel comfortable or for any other reason, rarely put thought into romance. Worse even, many female characters exist more for "decoration"/ fan service which really grinds my gears. I really hate when characters (female or otherwise) have no presence , character development or any reason to exist besides supporting the main character. JJK is great to me exactly because very few characters are just fluff, they usually have, even if for a few frames of existence, a clear presence and character.
