Fated Villain: Harem In A Fantasy World

(Currently participating in the Feb/March WPC contest) Zach walked out of a grocery store but was suddenly run-over by a runaway drunk driver. He spent months in the hospital, paralyzed from the waist down with no hope of ever walking again. However, he chose not to be sad by this, still believing that one day he would walk again. During his stay in the hospital, he befriended a nurse who had taken a liking to him due to the stories he read and retold to her. However, the nurse asked him a weird question out of the blue. “How would you feel if you ever got the chance to be transmigrated into a fantasy world?” Zach replied but he didn’t know the nurse was actually a Goddess. The next thing he knew, Zach woke up in the body of a cursed villain of a novel he read recently. In the novel, Zach Darkmoor was fated to lose not only his life but that of those he held dear as well, but with the help of the system, gifted to him by the goddess, Zach aimed to use his knowledge of the novel to not only change his fate but that of those he cared about as well. However, this doesn't mean he wouldn't be faced with forces that would try to stop him from achieving his goals.
