Shen Yan and Gu Yanzhi loved each other deeply, but because they were diagnosed with terminal illnesses at the same time, they hid each other and broke up.
Thirty-seven days later, they met again in the hospital - Shen Yan had terminal pancreatic cancer and Gu Yanzhi was in critical condition of leukemia. The two decided to give up treatment and go to the beach to spend their last days together.
But fate played the cruelest joke: Gu Yanzhi's illness was misdiagnosed and he was healthy; but Shen Yan's illness was real. What's even more cruel is that Shen Yan initially only had chronic pancreatitis that could be cured - those three months of giving up on treatment left no room for recovery.
She could have survived.
If she hadn't mentioned breaking up, if she hadn't pushed him away, if she had chosen treatment...
Unfortunately there is no if.
He is the only one who goes to the beach every year and writes her name in the sand.
