Bai Shu's world is so small that it can only accommodate two things: life and death on the operating table, and waiting for Qin Zheng to come home.
Later, half of his world collapsed. Qin Zheng is lying in the ICU and will never call him "Ashu" with a smile again. Amidst the ticking sound of the monitor, Bai Shu signed an organ donation agreement on his behalf - giving his heart to a teenager he had never met.
From then on, he had a habit of always subconsciously approaching the child named Lin Yan and listening to the sound of the heart beating in other people's chests. It wasn't until the young man's dependent eyes made him realize: he had almost turned his longing for one person into a bondage for another.
Some farewells don't require words, and some companionships don't involve physical presence. Bai Shu finally understood that true memory is to let the living live well.
Purpose: True love and remembrance are about learning to say goodbye, so that life can still find the meaning of moving forward after loss.
