Today's love between husband and wife has become thinner under the pressure of high-pressure and fast-paced life. Coupled with the long-term separation between the two places, the two endured grievances and had little communication. The man was indifferent and ran away from home, while the woman took on the responsibility of children and family work. She chewed the hardships and bitterness of life, fell and injured herself and licked her wounds and was forced to grow up. The two hearts gradually drifted apart and became colder and colder. Even the lingering hand-holding and love at the beginning have been eroded by the feathers of life bit by bit over the years, and they have become the most familiar strangers to each other. Only in the lives of a few couples can we still feel the brief beauty of breathing together. Finally, a feather came and crushed the 21-year shadow marriage.
