The book is adapted from real events and tells the story of a man who was detained by the police station for a night for a trivial matter, detained in a detention center for ten days, released on bail pending trial for four months, detained in a detention center for a month, and spent another year in prison. While living in prison, he also met various talented people, and there was a harem-like intrigue among criminals. Deep in it, he only thought about how to commute his sentence and get out of prison as soon as possible. But he had no chance to commute his sentence, but he caught up with the country's 70th anniversary and also caught up with the amnesty order. He was not released because of the amnesty order, but because of the country's 70th anniversary, his sentence was reasonably commuted, which also broke the record of short-term commutation in history. Because of this trivial matter, he experienced things and people that he shouldn't have experienced, and he also understood things that he couldn't understand before. He can now see things that were unclear before.
Intention: People only know how to cherish after experiencing suffering.
