Lily, whose words become law, is a lucky star descended from the heavens. She can bring good fortune to her loved ones. Her Master tasks her with finding her biological parents on Earth. While divining the appearance of Lily's father, her Master also foresaw danger for her mother. However, Lily has already found her father, Leo Wright. Leo, who currently has a girlfriend, is naturally baffled by Lily's sudden appearance and doesn't believe in her so-called power of 'words become law.' But as Lily speaks, Leo's body uncontrollably acts on her words. After catching his girlfriend cheating, a single sentence from Lily even makes Isabelle Beaumont—the richest heiress in Cloudcrest City and the top socialite—his wife.
