Matsumura Ryouko is a popular novelist in her 50s who has just found out that she has Alzheimer’s disease. In order to gain some fulfilment in her life, she decides to be a guest lecturer at a university. Through one of her students, she meets a South Korean exchange student, So Chan Hae. As they become closer, they fall in love.
It’s said that around 90,000 people go missing in Japan each year, and even overseas this phenomenon is known as “johatsu.” Burdened with worries, some young people deliberately choose to disappear from society, cutting ties with their current lives and erasing their personal information through “yonige-ya” (night movers) or “disappearance brokers.” Against this backdrop, a young man from Singapore comes to Japan and, together with his companions, struggles to rescue a missing girl — a “boy meets girl” story born from the shadows of disappearance.
