Sewol is on a mission to find a mystical plant that can cure her ailing sister Dewol. After a thorough search, she stumbles upon Hwawol Tang, a florist shop operated by Woonwoo. What Sewol doesn't realize is that Woonwoo is not an ordinary human, but a god who was once banished by the Jade Emperor, due to his past errors. Although Woonwoo cannot leave Hanyang, where he was exiled, he joins forces with Sewol to embark on a quest to locate the elusive perpetual snow ginseng. As they journey to find the herb, they must navigate their way through ghouls who cross their path. Can they retrieve the plant in time to save Dewol's life and regain the favor of the Jade Emperor?
