My Evil Stepson System Novel

Kevin Lannister receives a chance at reincarnation and a life of luxury, but his new existence is shattered when his mother is kidnapped and his father falls into a coma. Three years later, a twenty-year-old Kevin is murdered by a cannibal while attempting to visit his hospitalized father. Just before dying, Kevin is contacted by the "Evil Stepson System," created by the goddess of Happiness to turn him into an ultimate villain for revenge. Initially dismissive of the system's rudeness and perceived weakness, Kevin renames it "Parasite." In exchange for stopping the insults and acknowledging the system's dependence on him, Kevin agrees to help the system accomplish its mission of revenge against those who took his mother. The system readily accepts, presenting Kevin with his first mission: "Pop your cherry." This unexpected partnership sparks a burgeoning, albeit unconventional, alliance between Kevin and his new parasitic companion.
