When one door closes, a window always opens in its place. Yu Nana is a graduate student who has been pursing her doctorate degree in psychology for the past eight years. While her college friends have got married and/or have jobs Nana has been working hard to finish her thesis, which ends up not being approved yet again, leaving her without a PhD and feeling hopeless. The following day, Nana receives a strange email from Sasai Eisuke, a Japanese businessman who came across a photo of her on social media, asking her to go to Yufuin, a small idyllic town in Oita Prefecture in Japan (famous for its hot springs), to pose for some photos as Nana is his dead fiancee's a look-alike and he had no photos to remember her because she didn't like being photographed. In exchange for the photos, Eisuke promises to give Nana a ryokan, a traditional Japanese inn.
