Taming My Five Beast Stepsons

Office worker James wakes up inside a novel and finds himself in the body of Valerius, the vampire villain whose story ends with his death. The only thing waiting for him is a fate at the hands of five beastkin adopted sons, the very youths the plot has set against him. Instead of meeting that ending quietly, James must find a way to win over the five young beastkin who were meant to be his undoing.
