"My friend Yuta asked me to help him out by just meeting his parents for a blind date setup—he said it would benefit me too," Natsuki Tono's husband recalls. Since he owed Yuta for work favors, he couldn't refuse when Yuta asked to borrow his wife Natsuki to pose as his girlfriend. Natsuki reluctantly agrees and accompanies Yuta to his parents' home, expecting to return the same day. But to her surprise, Yuta's mother asks her to stay over during the long holiday weekend, insisting they spend several more days together. Even more shocking, they are told to share the same room—and the same bed.
