Min Kyungjin, a bright-eyed and relentlessly optimistic new hire, was thrilled to join the prestigious consulting firm <A&Z>, envisioning a typical corporate life. "Again." Little did she know her direct superior would be Jung Junwoo, the infamously demanding director of the Emergency Strategic Planning Team. Known throughout the company as 'Hades' for his icy demeanor and ruthless critiques, "Did you bring this garbage content and call it a report?" Junwoo had inadvertently built a solitary kingdom within his team. While colleagues whispered their pity for Kyungjin's daunting probationary mentorship, they hadn't accounted for her surprisingly resilient spirit. "Yes, I'll revise it immediately!" "I'm sorry, I'll have it corrected before the day ends!" "Another error? I'll fix it right away!" Kyungjin met the King of the Underworld's harshness with an almost unsettling cheerfulness. This unlikely pairing of the seemingly opposite <Hades and Persephone> soon finds their professional paths unexpectedly intertwining. As a series of unforeseen events unfolds, a curious attraction sparks between their contrasting worlds. Can the warmth of Persephone melt the icy heart of Hades? Their sweet and eventful office romance drama is about to begin.
