Moonbyul and Wheein have spent nearly their entire lives together, working towards their dreams of one day becoming singers. When faced with their dreams and success, however, they find that they have lost much more than they had gained. Having sold their youth in exchange for a chance at their dreams, the two now struggle to function, not knowing what to do as adults. Having ignored their emotions from the time they became trainees, as they had deemed emotions to be a luxury, they have now forgotten how to feel, when to feel, or what to feel. Now that they’ve earned their dreams, the only thing left is for them to learn what it’s like to be humans again.
