I've read this series up to volume 5, but publication ended with volume 6 while WNs stopped halfway through volume 10. My guess is, this was either axed or discontinued. I haven't seen the LN version of volume 6, but volumes 1-5 of LN were the same as volumes 1-5 of WN. The series wasn't that great, so the publisher might have decided to discontinue the series (and subsequently the author discontinued the WN version) or something might have happened to the author.

Volume 5 wrapped the bigger story of finding a cure MC's mom. Poster girl maid hardly appeared outside of the first volume. She was close with MC, but in a non-romantic way. During the 5 volumes MC gained 3 love interests, but he himself remained entirely uninterested in romance. Only at the end of volume 5 MC had romantic interaction with a girl that wasn't one-sided (and she was the most annoying of the bunch).

If I have the patience, I might try to continue reading, though discontinued status isn't very motivating.
