When Kevin tricks his wife ARIA into lending him her frost dragon Silvie, he uses it to seduce his mistress Lilian. Smitten, Lilian demands to take Silvie to a grand party at Dragon Valley. There, she spots ARIA—the classmate who once outshone her—and decides to humiliate her by flaunting the dragon. Lilian mocks ARIA mercilessly, never suspecting the truth. Because ARIA isn’t just a forgotten classmate. She’s Silvie’s true master, the kingdom’s secret princess… and Kevin’s wife. When Silvie kneels only to ARIA, Lilian’s world freezes. Now, her worst nightmare is just beginning.
