Kokoro Hasegawa 長谷川心

A young aspiring, hard-working fashion designer, first-year student at the Geika Institute of Fashion, and part-time model at "Bon Rouge". She has a shy, submissive, and meek personality, and is rather self-conscious about her height, though she became less bothered by it when she was scouted in high school.

Despite being talented as a model, Kokoro dislikes the nuances the job includes, but her feelings of debt towards her manager Igarashi and her lack of confidence prevents her from quitting. Upon befriending and working alongside Ikuto at Yanagida's studio, Kokoro gradually begins to be more courageous and challenging herself due his encouragement, though she is still prone to self-doubt and worries.
