In my culture & religion, it was permitted to have polygamy in a marriage. There was actually a man who his wives actually planned for him to get married to until the limit quota (four wives per one family head/husband) because he was a very unassuming, kind & just person. He didn't even try to seek them because he could/wanted to, but his wives by their own judgment wanted him to marry the next woman (that needed a man's protection) due to his own pure personality. It's a true story (from the 90s as I remember correctly) as well as a very VERY rare occasion due to the hard accomplishments the men in my culture must achieve in order to even marry more than one woman for whatever valid reasons. But the bonus of this moral of the story was that all of his wives were either widows or had their own circumstances, self-efficient & they're all friends with each other, thus they wanted him to help provide them shelter & care & at the same time closer friendship & familial values. This MC reminds me of that legendary man, except that they're not as young & this was real life.
