Haejun is a 20-year-old student who has been held back. His father is Elon Musk. He is foul-mouthed and extremely violent. Once he gets triggered, he throws a massive fit and beats his opponent into a knockout. Haejun has a completely rotten personality, showing no mercy regardless of whether someone is a woman or an elder. One day, he even approached an old woman collecting scrap paper and sold her haul as parrot toys. He constantly smokes on the street and spits all over the sidewalk. He only attends school once a month, and even then, he spends the day sleeping or just escapes. Because of this, he fails every year.
