(Ahem, pure love, no knife, feel free to eat)
Lin Zhiyi was diagnosed with a terminal illness and only had three months left to live. She chose to spend her last days traveling around the world, and when she was watching the Aurora in the North Cape of Norway, she met Lu Yanshen, a similarly lonely traveler. Two broken souls fell in love under the aurora, but they didn't know that this encounter was a cruel countdown. When Lin Zhiyi's condition suddenly worsened, Lu Yanshen discovered from the diary she left behind - she had long known that she would die, and every day they spent together was the result of her secretly stopping a medicine.
