Yumi's Cells

Controlled by a complex network of cells, each and every human on the planet is kept running by an unseen operating system that is, for the most part, completely ignored. Though humans never give much thought to how they manage to function, day in and day out, the cells within the human body are constantly at work, doing their part to keep their human alive and well. Which is why on the outside, Kim Yu Mi may appear to be just like every other single working woman in the world, but underneath that ordinary exterior lies something truly extraordinary.
