Your Wife... Can I Borrow Her For One Night? Ayaharu Natsume

"I want to see my grandchild." "Aren't you married yet?" I was sick of it. Fed up, I blurted out, "I'm seeing someone with the intention of marriage." I thought that would calm things down, but now it's "Bring them here soon!" "When are you going to bring them?" a storm of demands. For something like this... there's only one person I can ask. "Can you lend me your wife... just for one night?".
