Honestly? To me... Not a "bad" read. Lots of senseless fun and hilarity. Just an isekai where the protag is given a "useless" skill, NOTHING is explained to him, and he has to make do with TRYING. I doubt there's any REAL meaning behind the entire story. Lots of childish fantasy mixed with a little suggestive overtones with the MC getting nothing, but all his FLs want him.
MC alone is about as "strong" as a villager, far weaker than 90% of all the FLs.
