polygamy isn t just about sex tho?
Polygamy means multiple marriages, and usually its related w/ religion, and communication is not a key factor. meanwhile, polyamory doesnt have to be a marriage (it can but its based on relationships and doesnt really have to do with religion). So based off of that, the relationship in the manga is definitely not polygamy
see a lot of people calling this relationship polygamy, but isnt it polyamory? they focus more on communication than just sex, sex, sex.
