as a yuri-ist, I read into the comment "she's away with her lady's club" as a swinging lesbian retreat (omg the other wife, silent at the dinner table, like a damn fish, so bad! so so bad!)
I just pity the wife at this point, she's working so hard but she gets cheated on instead of the husband trying to communicate with his wife properly about his thoughts
He got went back to earth and got male humans as the other alien's wife, bro made them had the same fate (from what I understood)
Was still a good read for smut though
I think those people he brought humiliated him on earth and that's why he come to journey alone... That's why he brought them here.
That makes sense tbh
