Four Heavenly Kings

In the world of the web novel, every middle school and high school in Korea has a "Four Heavenly Kings" set. The Four Heavenly Kings are typically the most popular and handsome boys in school. They are also typically incredibly talented in some way, rich or sons of conglomerates, and have unusual hair and eye colouring. There do exist schools without Kings, but they are rare in this world.

These types of characters are generally adored and revered by the school population, treated like idols or actual kings. According to web novel tropes, any girl becoming friends with these characters are bullied and treated badly by other students

Since they are the "heroes" of the web novel, these characters are also friends or related to each other in some way.

The "Four Heavenly Kings" is taken from the Buddhist belief in four gods that rule over the four cardinal directions. In anime/manga/video game, it has come to refer to groups of four people who are unbeatable in their given field, according to the context of the canon. In romance web novels, this would describe groups of extraordinarily beautiful, intelligent and talented people.

Kings of Ji Jon


The Four Heavenly Kings of Ji Jon Middle School, where the story of Inso's Law starts, are: Eun Ji-ho, Woo Ju-in, Kwon Eun-hyung, and Yoo Chun-young. They are the "main characters" that Dani befriends. According to the tropes, Eun Ji-ho and Woo Ju-in are childhood friends, and so are Eun-hyung and Chun-young.

Kings of Seokbong
The Four Heavenly Kings of Seokbong Middle School were Shin Seo-hyun, Yoon Jung-in, Kim Hye-woo and Kim Hye-hil.

Although appearance-wise, these characters do not fit the characteristics of "Kings" (i.e. unusual hair and eye colours) - all four of them have brown or black hair and eyes, with the exception of Seo-hyun who has golden eyes - they still fit the other characteristics. Seo-hyun is a talented athlete, while the twins are incredibly intelligent and high-scoring students. Only Jung-in is implied to be 'normal'; but he, like Kwon Eun-hyung, is always the "class president" in his class.

Although Hye-hil is female, she was also considered part of the group because of her beauty and because she is Hye-woo's twin. Seo-hyun and Jung-in are childhood friends. Despite being considered the Four Heavenly Kings in their middle school, the four of them aren't friends together. They were only in the same class with each other in the final year of middle school.
