★ A growth story that encourages children to bravely "be themselves." Children are always taught to "become" a certain ideal, yet are rarely asked, "Is that really what you want?" This is a story of truly "finding oneself" in the pursuit of "becoming."
★ The courage to "be yourself" matters more than becoming a "dragon" in others' eyes. Imoogi, on the journey to become the 999th dragon, undergoes training and confusion, learns to listen to the inner voice, and ultimately discovers that being the true self is more important than becoming a dragon.
★ Full of laughter and touching moments, the book includes a fold-out screen-style minibook featuring two versions: "Top Secrets to Becoming a Dragon" and "Top Secrets to Becoming Your Cool Self," extending reading into hands-on play, ideal for parent-child interaction and self-exploration activities.

Young Imoogi dreams of becoming a dragon that everyone admires. Following an ancient manual, Imoogi begins training: controlling anger, letting go of greed, and solving puzzle-like tasks one by one. Yet the first chapter alone is full of challenges. Though Imoogi earnestly completes every task, a growing emptiness sets in, so Imoogi stops to do what truly brings joy: traveling, swimming, dancing.

A question then arises: "Do I really want to become a dragon?" Imoogi, who has always been running toward goals set by others, listens to the inner voice for the first time. Standing before the Milky Way, Imoogi makes the final choice. In the end, Imoogi discovers that finding its own path matters more than becoming the 999th dragon. Through Imoogi's journey, this book explores the choice between following others' expectations and being one's authentic self.
