Mihwa spent three decades as a medical expert witness specializing in brain injury—a career built on precision, high stakes, and unflinching detail. Then her young daughter developed an insatiable appetite for bedtime stories, and Mihwa discovered she could spin new ones on the spot, endlessly, a habit that hasn't stopped since.

She has published spicy historical romance novels, both through self-publishing and Dragonblade publishing. Her fans say they come for the uniqueness and humour but stay for the emotional resonance. Mihwa also writes across genres and is represented by literary and film agents at Jabberwocky Literary Agency.

Despite all this, she is primarily known as Birth Giver who deep cleans, Birth Giver who counsels at 2 a.m., a short-order cook, and short.
