The most painful thing in the world is when you ask for something but can't get it, when you love something but can't, when you can clearly reach out and touch it, but there is a separation between yin and yang.
In Jiang Mu's youth, there lived a young man named Chen Chi. He accompanied her through the cicadas in the midsummer, and stayed with her through the cold window to study hard. He promised her a long life, but in the end, in the warm spring of 24 years old, she was left alone in the world without him.
The fortune teller's saying "life is short" was once treated as a joke, but in the end it became a sharp knife that penetrated everyone's heart. After Chen Chi left, Jiang Mu stepped on the edge of the underworld just to find him. It wasn't until the young man in her dream asked her warmly that she held on to Yu Wen and lived well for his sake.
Until she met Xiao Yan, the face that looked exactly like Chen Chi became the driftwood she grabbed onto when she was drowning. She pursues her desperately, and he responds without knowing it. A marriage that started as a substitute, wrapped in lies and obsession, slowly reveals its true feelings over the years.
When the truth tears through the disguise, when guilt overwhelms love, when she is finally ready to reconcile with the past and stay with the person in front of her, fate is no longer merciful.
Two unsent letters hide her last struggle and tenderness; a figure who has been guarding her for a lifetime has turned her love into eternal loneliness.
It's late at night, the inkstone is cold, and the love and regret in this world are finally scattered in the wind.
Concept: Love is a mark engraved in the bone marrow, and a substitute is a cage of self-deception. Some people are trapped in the residual warmth of the deceased, and some are addicted to false tenderness. When the truth tears through the disguise, regrets and misses will eventually become lifelong sorrows. Only parallel time and space can complete an unfinished perfection.
