Always ignored, always forgotten, always haunted by malice. An unintentional joke almost resulted in the loss of his father, but the result of his desperate efforts to save him was the protagonist's death with a smile on his face. Perhaps it was God's blessing that he found that he had returned to the days seventeen years ago, the year before he was born, when his father still lived with those two people. Change, ignore, or quietly wait for this ghost to dissipate! Follow the figure of the protagonist and quietly watch the story unfold. It turns out that everyone is a book, and the only difference is who is reading it!
