When the emergency room monitor's beeping rang out, I heard the shortest forever you ever promised me.
“If my breathing is destined to stop, let the seventh second become an eternal measure of time, one I can use to love you.”
Gu Tingyuan, a cardiac surgeon, is best at outmaneuvering death. But in the emergency room, he meets the one “case” he can never cure: Shen Tingxi, a volunteer in a drug trial. With a rare disease counting down her days, she has reduced her life to cold numbers. Yet at the instant her heart stops for seven seconds, she collides with him in an absurd moment of tenderness.
He tries to slice through fate's cocoon with a scalpel, but she has already wagered herself in the drug trial. Love and lies intertwine with the sound of the ventilator. Love letters hide in medical folders that were never sent, and every revived heartbeat pulls them deeper into a love neither can escape. Only when she stops breathing in his arms does he understand her final letter:
“You always say the seventh second is a miracle of life. But it was the only stolen moment of my life, and I used it to remember your eyes.”
When the tide swallows their final goodnight, the one they love becomes an echo on the far shore.
