I don't know exactly who said it. It could have been a protagonist who came to this realization after going through a series of challenges and learning lessons about the futility of revenge.
One reason it stands out is the detailed world-building and the unexpected turns in the plot. Also, the character development is really well done, making you root for the protagonist throughout the story.
First, identify the variables from the true story. For instance, if it's a story about a student's academic progress, variables could be study hours and grades. Then, collect relevant data on these variables. After that, use regression techniques like linear regression. If the relationship seems linear between study hours and grades, the regression model can show how changes in study hours are likely to affect grades.
In these fanfictions, age regression can completely transform the characters. Yang, who is strong and confident, could become more vulnerable and in need of protection. This change can lead to new character dynamics. Blake might show a more playful side that was hidden before. Also, it can affect their decision - making abilities. The characters may make more impulsive decisions like a child would, which can create new plotlines and story arcs in the fanfiction.
One common theme is recurring relationships. For example, people often claim to have had the same group of family members or friends in past lives. Another theme is unfinished business. It could be something like a task not completed or a wrong not righted. Also, the experience of living in a particular historical era is common, like being in ancient Rome or medieval Europe.
Well, a man age regression story might be about a man who has a mid - life crisis. He starts to feel that he has missed out on a lot in his youth. So, he decides to take a break from his normal adult life. He enrolls in extreme sports classes, which he was always too scared to do when he was younger. He also changes his diet to the junk food he loved as a teen. His relationships change too, as he becomes more carefree and less responsible in some ways, much like how he was in his younger years.
