Unknown near future in South Korea, selective euthanasia becomes legal. The main character's grandmother (who had lived her life head-strong) announces to the family that she's putting a lifespan plan and will be ending her life in 5 years. The family goes through strange five years untangling, tangling emotional ties with the grandmother.
The story is about death, but it's empowering. Imagine how individual can set a limit to their own definition of 'life', 'life quality' and plan your exit. Wonder how many people can actually go through the process without fear, uncertainty no matter how old you are.
