The novel is about the male protagonist and the female protagonist who got to know each other because of the female protagonist's friends in the summer when they were in junior high school but not in the same class. The male protagonist's buddies happened to be in that class and fell in love with the female protagonist's best friend. Naturally, they got to know each other, which is fine because the female protagonist likes to be alone. It's not because of the female protagonist's best friend that the female protagonist is now. It's definitely not as good as it is now. Before the male protagonist confessed to the female protagonist, something happened in their family. The female protagonist's father said that the anti-narcotics police were often in the drug dealers' den, but he chose to keep it a secret because of the country. The female protagonist's mother thought he was making dirty money, so they divorced because they were afraid of being implicated. The female protagonist's temperament changed from the good girl before to a gangster. The male protagonist slowly brought him out of this mood, which gave the female protagonist a new life.
