I don't know, which girl I like less the walking inventory space or chuuni almighty. Both don't have much of a personality to speak of and the way they talk is really annoying. I hope it will get better in later chapters.
I can already tell that item girl is acting... hard. She's probably the worst and given the info that its to make parents and children get along and you can't leave before that she and her mom got into a fight.
@Harry_Dong the merchant girls mom is allowed to log out to go to work since her job is so important apparently. Only job I can think of like that is a doctor, surgeon, important researcher or important engineer. Those are some of the only jobs that directly deal with saving lives, keeping people alive and improving standards of living. Though I do imagine their moms aren't that great like MC mom is
