Lin Chen, a twenty-two-year-old college student, is diagnosed with a rare terminal illness and has only thirty days left to live. He chooses to drive away his beloved girlfriend, Su Nian, with a lie, asking his former rival in love, Lu Yu, to take care of her. Each day, he quietly rides the bus, using sixty tickets to piece together a silent farewell. When the truth comes to light in the rain, Su Nian finally understands that behind all the hurt was Lin Chen's deep love, keeping watch over her alone so she could have a happy future. After he is gone, he leaves behind more than tickets soaked with tears: he leaves her the courage to start living again. Carrying his blueprints, Su Nian builds the house of his dreams by the sea, letting his brief life continue in another way. Love cannot defeat death, but it can transcend it.
