Metamorphosis:- Franz Kafka

The story begins with Gregor Samsa, a hardworking traveling salesman, waking up one morning to find that he has transformed into a huge insect-like creature. He does not understand how this happened, but instead of panicking about becoming an insect, his first worry is that he will be late for work.
Gregor was the only earning member of his family. He worked a job he hated to pay off his parents' debts and support his father, mother, and younger sister, Grete.
When his family sees his transformed body, they are horrified and disgusted.
His father becomes aggressive and violent toward him.
His mother is shocked and helpless.
Grete, who at first cares for him by bringing food and cleaning his room, slowly becomes tired and resentful.
As Gregor becomes unable to work, the family is forced to find jobs and support themselves. Slowly, they begin to live without depending on him.
Gregor becomes isolated in his room, ignored and treated like a burden. His physical condition weakens, and his emotional pain grows as he realizes his family no longer sees him as human.
The turning point comes when Grete finally tells their parents that the creature is no longer her brother and that they must get rid of it.
Hearing this, Gregor feels heartbroken and retreats to his room, where he quietly dies.
After his death, instead of mourning, the family feels relieved. They go out together and begin planning a brighter future, especially for Grete, who has grown into a young woman ready for marriage.
