How to survive as a villain

Ren Jiang, an introverted architect, died. He found himself transmigrating into a psychotic villain of the novel he read. Thinking about gaining new martial powers, he excitedly stepped out of the door. He did not get the powers but ended up face to face with a childhood friend who was obsessed with the original body. Ren, "..." Trying to get rid of the obsessed friend he found himself entangled in life and death situation with none other than the male lead. Ren, "... Please, leave me alone!" With the help of his system, Ren, now, Dorion, tried warding off the evil people and correcting original's evil ways. He finally achieved a peaceful life.... Not really. Even, when he carefully avoided any troublesome interactions with the main leads, he still, ended up catching the eye of the male supporting character. A person who appeared at the end of the novel, just to torture the original Dorion. Even when the original owner begged for death, he was cured to be tortured again. Ren, "..." Looking at the tall figure coming towards him, Ren sneakily tried to wiggle his way out, "I'll l-leave right now. I-I didn't m-mean to come here…” Kade Death laughed, his wine-red eyes gleamed with amusement. He easily trapped the beautiful person in his arms, "My sweet, you didn't actually think that I would let you go, right? The scared Ren, "..." I did, But I dare not say! "I let you go once, angel, not anymore..." Ren, "...System, H-Help!" System, "Why don't you help me?!!!! Save me from the claws of this nine-tailed fox!!!!" ---------------------------------------------------------- "It's a slow burn. You have been warned... There will be smut... but at later parts.
