A girl dying of pancreatic cancer befriends a bookworm loner, and the entire film is built to make you feel the weight of every moment they have left together. It refuses to look away from the cruelty of loving someone with an expiration date. The ending will devastate you not because it's shocking, but because you've spent ninety minutes understanding exactly what's being taken away.

A detached bookworm finds a handwritten diary in a hospital waiting room. The title on its cover reads: "Living with Dying." Inside, he discovers the journal belongs to Sakura Yamauchi, a popular and cheerful classmate. Her bright exterior hides a secret: she has a terminal pancreatic illness and only a few months to live. Apart from her family, he is now the only one who knows. He promises to keep her secret. Rather than withdraw, Sakura resolves to live as normally and fully as she can until the end. Though he shows her no sympathy at first, her persistent optimism wins out, and he agrees to spend her remaining days with her. Her carefree, unpredictable nature slowly unsettles his indifference to the world, and his heart begins to open. The film is a quiet drama and romance about two classmates with opposite personalities whose bond deepens with each passing day.
