This is a collection of short stories that contains the sorrows of the world. Each chapter hides an emotional past that was torn apart by fate - maybe it was childhood sweethearts lost in time, leaving only old things to reflect unspoken love; maybe it was lovers separated by life and death. Hope, only the undelivered letter is left wrinkled in the wind; maybe brothers turned against each other due to a misunderstanding, and they were estranged for half a lifetime when they met again; or maybe best friends and best friends drifted apart over the years, and those former close friends finally became a thorn in the memory.
There is no happy ending here, only the sourness of not being able to love, the pain of being separated from yin and yang, and the lifelong regret of misunderstanding. Each story opens up the softest corner of the human heart, letting those late farewells, unspoken sincerity, and unrecoverable past repeatedly pull between the lines, poking everyone who has left regrets in their relationships.
