Fare well, nameless sixth husband. You are truly a man. You are corteous to the end, your word is a contract, you'd never allow a woman to suffer because of you, you protected both honor and happynes of your wife, you see through everything you start. You did it all for its own shake, not expecting any reward. You are a paragon of non-toxic masculinity. You are what John Wayne wanted to be when he grew up. May you find a loving wife such as you deserve.
If Mori-sensei does write you finding your loving wife, good.
And if she does not write you finding her, and unless she actually writes you dying without finding one, BETTER, because that means that your story is mine to write, and so I'm writting here that you did indeed find a beautiful, inteligent, loving, faithful, skilled, and (why not) rich young wife on your way back home - one who one day you confided with this tale and as result she fell even MORE in love with you.
Que cojones. You deserve it.
