Because his wives can’t bear him a son, he’d divorced them, one by one, and, the reason he’d found them to marry one by one, was because he’d wanted to have, a “male heir”, someone, to carry on his family’s last name…

Because his wives can’t bear him a son, he’d ordered to have their heads chopped off (like in Henry VIII???).  Without EVER knowing, that he’s the problem, when all his wives (one after another!) couldn’t have a son, because of H-I-M.

Because his wives can’t bear him a son, he’d gotten rid of all of them, and, after a dozen wives later, he’s still, child-less, and, as he’d become, elderly, he looked around for someone to love, and, he couldn’t find one, even the DOGS had left him!
