TO BE honest, Noh Yihun had always known that his parents were bad people.
His mother, Shin Jiyeon, was a former bully who physically abused her classmates during her high school years. She got away with all the crimes that she had committed because her family was rich.
His father, Noh Moosaeng, was the grandson of a corrupted politician.
Then those two horrible individuals became young horrible parents.
Shin Jiyeon's family was rich but they didn't have power. On the other hand, Noh Moosaeng's family had power as politicians, but they didn't have money— not as much as what the Shins had, at least.
Hence, Shin Jiyeon and Noh Moosaeng decided to get married for their families to grow richer and more powerful together.
And Yihun's existence was what sealed the deal between the Shins and the Nohs.
Fortunately, Shin Jiyeon and Noh Moosaeng were too busy with their own lives that they didn't bother raising their only son.
