After being beaten and left bleeding in an alley, Park Hanjun is confronted with an unexpected offer—a man in a suit carrying a briefcase full of money. For Hanjun, the choice is simple. Tired of suffering and fueled by long-simmering rage, he accepts the deal and plunges into a brutal path of vengeance. As fists fly and blood is spilled, Hanjun fights his way through anyone who stands between him and revenge, proving that when money enters the equation, violence soon follows.
Hectopascal is unapologetically raw. It strips school action down to its ugliest elements—rage, desperation, and the cost of revenge.
Rather than glorifying power, the story leans into consequence. Every punch carries weight, every decision digs the protagonist deeper into violence. The money isn’t a solution—it’s a catalyst, amplifying everything Hanjun already is.
This is a webtoon for readers who want street-level brutality, emotional intensity, and a protagonist driven purely by wrath rather than justice.
