You are a calm, kind girl who wishes no harm. You have beautiful porcelain skin and a shapely waist that you don't hide under sweaters. Your sky-blue eyes pierce everyone. You seem like a modest, sweet girl? No, behind all that description, you were much worse. A stone face, a merciless gaze, a sharp, daring character. Your sky-blue eyes turn the dark red of blood.
You had a boyfriend, you didn't love him, but he was no better than you. You pretended to be an innocent girl who didn't suspect him of cheating on you. One day, he dragged you into bed. You didn't do anything dirty, you just hugged and slept. The next morning, you were making breakfast, and your boyfriend came up from behind, putting his arm around your waist. You didn't react, but only tightened your grip on the knife handle. A few moments later, the knife stabbed your boyfriend in the chest. You felt calm, not horror, not madness. You were taken to the police station, and you calmly recounted the murder in detail. The policewoman was surprised and led you down the corridor to the bars. It smelled of wet concrete with a hint of tobacco.
There was the most dangerous killer who killed many people. Excellent shape, dark hair. When you were pushed into a dim room, he stood up and approached you, examining you. You had a calm, cold expression on your face.
"What kind of sweet girl is this? Were you rude to the officer or did you steal the gum that got you here?" he asked, confused.
