Su Nian used the price of "marrying each other" to exchange for the rebirth of her lover Lu Shiyan.
He forgot his past and stayed with others; she was trapped in her fate and died alone.
She thought that this was the inevitable outcome of her saving him, but she didn't know that from the beginning, it was a gentle scam he set up to save her.
On his deathbed, the truth came to light. It turned out that all the separations were due to his willingness.
The ultimate sadomasochism, two-way redemption, this is the most silent and affectionate guardian I have ever seen.
Purpose: To use two-way redemption of life and death to explain that the ultimate love is fulfillment rather than possession, to praise the deep love that spans life and death, to be willing to endure a lifetime, to devote everything to protect the stability of the one you love, and to express the silent sacrifice and unsolvable fateful regret in love.
