This film is adapted from a love novel of the same name, which was nominated by Yukio Motogu and Yukio Mishima. Severe narcolepsy made Ning Zi spend most of her time in bed, so she gradually became a squat at home, almost cut off from the outside world. Her boyfriend Zinaimu, who lived with her for three years, was once an aspiring young man with a literary dream, but he was smoothed out in the process of being an editor of gossip magazine, just commuting to and from work like a machine every day, buying a bento to bring Neiko who could not come out of the door. The life of stagnant water has been changed by the visit of Tzunaimi's ex-girlfriend Antang. Antang is still unforgettable about Tsunami. In order to recapture Tsunami, she began to actively help Ningzi get out of the house and adapt to society.
