Jiko Bukken to Kanojo no Saigo no Hi

Fumie, a woman in her 50s who has been told she has only six months to live, quits her job and buys a rundown, accident-prone property as her new home. She thought it would be fine as long as it could withstand the elements, but ends up asking a friend of hers, Ume, to help renovate it. Fumie, who wants to die peacefully, begins her somewhat strange new life.
