Within a Rose

Although they left the house to him, he finds himself very lonely by himself and wishing for someone to live with him. While cleaning his parents' closet, he finds a magic rose, accidentally releasing a dark fairy named Desdemona who was imprisoned centuries ago for attempting to kill the daughter of a king and queen. Wally must get used the new addition to the his household (who insists on staying) and introduce her to the time period she finds herself in. He also has to deal with Desdemona's constant flirting which flusters him to no end.
