When the emergency room beeps, I hear you say the shortest forever
"If my breathing is destined to stop, let the seventh second become an eternal mark to love you."
Cardiac surgeon Gu Tingyuan is best at playing games with death, but in the emergency room he encountered an incurable "case" in his life - drug trial volunteer Shen Tingxi. With the countdown of a rare disease, she cut her life into cold numbers, but at the seventh second when her heart stopped, she encountered an absurd tenderness with him.
He tried to cut through the cocoon of fate with a scalpel, but she had already sacrificed herself to the gamble of drug trials. Love and lies are intertwined in the sound of the ventilator, love letters are hidden in unsent medical records, and every resuscitation of the heartbeat is a deeper sinking. It wasn't until she stopped breathing in his arms that he read her last letter:
"You always say that the seventh second is the miracle of life, but that is the only time I steal in my life to remember your eyes."
When the tide swallows up the last good night, the one you love deeply becomes the echo on the other side.
