Do Jeongyoon began writing through poetry and went on to work for many years as a copywriter and creative director. While crafting countless advertisements and messages, she has reflected on how language leaves traces on people’s emotions and choices. She currently teaches copywriting at a university. Stepping back from persuasive language, she now focuses on writing that explores the fundamental emotions and attitudes that shape human life. This book represents a turning point in her language—refined through poetry, advertising, and education—moving beyond speed and efficiency toward contemplation and reflection, and offering a calm yet profound perspective on Korean life.
