"As expected of the hero, your lower half is brave too lol"

The final battle against the Demon King who plots world conquest. However, the hero party is on the verge of a fragile defeat before the Demon King's overwhelming power. But at that moment, the Demon King makes a proposal in exchange for abandoning world conquest. Shockingly, it is: "The hero must declare which member of the harem party they will marry in the future!" Note that polygamy is not permitted in this world. What will the hero do!? ※This is in script format + absolutely hilarious, so please skip if that's not your thing!
