What does the author reveal about his own personality before he started writing, and how does it relate to the name 'Hemadpant'?

In Chapter 2, the author provides a candid self-assessment of his character before his transformation. He describes himself as initially being mischievous, talkative, cynical, and critical, with a logic-driven mind. He was "always proud of his own wisdom" and prone to argumentation. He promises to tell the story of how he was named "Hemadpant," a name that appears at the end of every chapter. He suggests that understanding his argumentative nature is key to appreciating the appropriateness of this naming ceremony, which he presents as a sub-story within Sai's life story, inspired by Sai Himself to satisfy the reader's curiosity.
