Mina Morishita is a chubby office lady who works at a company and struggles with her weight. She has never been able to see results from her desperate dieting, and because of her short stature of 152 centimeters and weight of 62 kilograms, she has never been treated as a woman by those around her. Her motivation stems from a desire to be seen as feminine and desirable, a feeling that has eluded her due to her body type. The first person to treat her as a girl is the company's most popular elite section chief, which becomes a pivotal relationship in her story. This relationship drives her character development as she experiences romantic attention for the first time. Her notable trait is her persistence in trying to improve herself despite repeated failures, and her personal growth centers on gaining confidence and self-worth through this newfound affection.
