In the spring of the 26th year of the Republic of China, Shen Zhaotang sang "The Peony Pavilion" at Zhaoyue Tower and met Gu Yuncheng.
He is the cold-faced major that everyone in Peiping fears, and he is also an intelligence agent who walks in the dark.
He didn't send flowers or write love letters. He only gave her a bowl of pear soup after every scene.
Shen Zhaotang thought he was ruthless, but later found out that he hid all his tenderness in secrets that could not be told.
They made their promise under the crabapple tree.
He said: "When the crabapples bloom, I will come back to marry you."
But troubled times don't allow people to reunite.
Later, the crabapples bloomed every year, and the people who returned never returned.
Many years later, white-haired Shen Zhaotang returned to the stage and received a belated letter.
The letter read: "I should have returned when the begonias bloomed."
At that moment she realized that Gu Yunzheng had never failed her.
He just died on his way back to marry her.
