Am I really just a side character?” Veil muttered to himself.But why should he accept that fate? His father held absolute power, his mother was a legendary business tycoon—what made the so-called protagonist superior to him?Fortunately, at that moment, he successfully awakened the Villain System.One day in the future—“Veil! You crippled me, stole my opportunities, and even took my woman! You damn villain! You’ll suffer divine retribution for this!”A protagonist roared in fury, coughing up a mouthful of blood.Veil smiled gently and said, “I didn’t do anything… This was simply your fate.”“A pawn has only one destiny—to be placed exactly where I want it.”Remember this.I, Veil Lancaster, only wish to be a charming and sinister villain.
