He is Lu Zhimou, a dazzling yet aloof young man.
She is Ruan Zhixia, a quiet, fragile girl hiding a serious illness.
A chance encounter as deskmates by the window lets him glimpse the pain and tenderness beneath her pale face. From then on, he gives all his favoritism and protection to this girl, who must even be careful with every breath.
Her heart has shackled her all her life. She cannot run or jump. Her greatest wish is simply to see the sea once, and her most extravagant hope is to love him once while healthy.
He stays by her through one attack after another, keeping watch over her medicine and oxygen, and making countless promises of a future together. Yet he doesn't know that her life is already counting down.
The seaside, where she smiles brightest, is both the end and the farewell.
She slips away without a sound, leaving him to keep watch over an empty seat, the lingering scent of old medicine, and a lifetime of regret he cannot let go.
Her life is as fragile as paper; his love runs so deep he follows her into death.
In life, he stays by her; in death, he follows her too.
Summer ends, and dusk falls.
In this life, I will not fail you; in life and death, we shall go together.
A devastating love that begins in youth and reaches the underworld, offering life itself as its sacrifice, ends at last in another world, where they will never be apart.
