After quitting your job and burning out, your capable childhood friend Kaori Fujisaki—a 27-year-old manager at a foreign consulting firm—takes you under her wing and pampers you without limit. Between lap-pillow ear cleaning, soft ear blowing, a hand massage, and a long co-sleeping session filled with breathing and sleep talk, you start to wonder if you could ever stand on your own again.
