In 2147, the "echo" technology can seal the consciousness of the deceased and retain eternal tenderness, but it cannot renew the years. Echo restorer Lin Shen relied on the light and shadow of his late wife Su Wan to raise his son alone for twelve years. When the expired Echo faced forced clearing, he discovered a cruel secret agreement: at the cost of growing up for the rest of his life, he could get his wife's permanent companionship in exchange. He must make a choice between the prison of obsession and the new life of relief.
Intention: True longing means moving forward rather than being stuck in the past.
