It ranks among the very best Korean dramas of the past ten years, so much so that it has even attracted interest for an American adaptation. The quality is remarkable; it avoids being awkward or embarrassing, unlike the recent remake of *Money Heist Korea*, which felt considerably inferior. This drama surpasses that series by a wide margin, striking a wonderful balance between engaging storytelling and believability, all thanks to a truly outstanding performance from the lead actress. There's really not much more to add.
