Hatoko returns to her hometown in Kamakura for the first time in 8 years and inherits her late grandmother's stationery store Tsubaki Bunguten. However, the shop exists only in form and is actually a notary public which writes letters on behalf of others. As a newbie in this trade, Hatoko gradually becomes better at writing various types of letters with the best words to convey the clients' feelings to the recipients. Through her work, Hatoko's heart gets filled with satisfaction and joy which inspires her to make changes to her life.
