糟糕，我亲手培养了大反派！

Oh no, I personally raised the big villain! After an unexpected turn of events, I became the protagonist of a revenge novel—the most powerful mage, Nils Glaray. I had planned to start my own slacker life, but I accidentally picked up the temple knight Havier, who kills me in the novel. A moment of weakness led to a lifetime of trouble. Can anyone tell me why the cold and ruthless Havier from the novel is so "clingy" in reality?
