At first glance, Yoo Sangah seems like an ideal protagonist who is almost "too good to be true". Though her most outstanding qualities are her "hard work, sincerity, and patience",[8] she is also known to be affable and kind-hearted. Her general competence and conscientiousness led her to be called a model employee at Mino Soft. In all aspects of life, Yoo Sangah always tries to do the best she can, as she has a vested interest in self-improvement, taking initiative to learn new skills on her own. She is a lover of literary fiction (e.g. Haruki Murakami, Raymond Carver, Han Kang),[9] health-conscious and places value on her appearance. Though initially presented as a neat and well-adjusted woman who managed to fit perfectly into society, it quickly becomes clear that this is not quite the case.
