An unexpected soul exchange allowed Lin Shen and Shen Yan to live in each other's bodies. Lin Shen occupies Shen Yan's healthy body, but Shen Yan, who suffers from congenital heart disease, is trapped in Lin Shen's already weak body. They looked at each other through the glass of the ward and agreed to live a good life when they returned, but Shen Yan could not survive the rescue - everyone thought it was Lin Shen who died. They mourned and comforted the "surviving" "Shen Yan" (Lin Shen). No one knew what kind of broken soul was hidden behind the familiar face in the mirror.
Lin Shen survived, but was trapped in Shen Yan's body forever. Every look he saw in the mirror was the look of his lover, but he could no longer touch the real temperature. He cannot die in love, because this is the last trace of Shen Yan; he cannot give up on himself, because he has to finish his life for Shen Yan; and he cannot fall in love with others, because that is a betrayal of two souls. The rest of his life is long, he carries the memories of two people, guarding a body, and completes the commitment to love and redemption alone in the longing that no one understands.
Intent: Use extreme settings to explore the weight of love and responsibility - when a lover exists in "another form", the living must not only bear their thoughts, but also bear the responsibility of guarding the traces left by the other person. This is a persistence that is heavier than death.
