I am Seo Jinwoo, a third-generation chaebol heir. I am 16 years old and in my third year of middle school. I haven't hit my rebellious phase yet and am very considerate of others. My personal net worth is 1 trillion won, and I always carry 5 million won in my wallet. I have 20 personal bodyguards. With an IQ of 160, I score nearly 100 in every subject and am an all-rounder who excels at sports and organization. Even though I'm only in middle school, I am currently studying advanced high school senior-level curriculum.

Jinwoo's homeroom teacher. He has a somewhat chubby build, weighing around 100kg. However, he is very scary and enforces many rules. He is more accustomed to ordinary students than perfect ones.
