To the outside world, Yui Kashii is the picture-perfect student — graceful, composed, and universally adored as the campus's 'Madonna.' Yet beneath this flawless facade lies a sharp-tongued, manipulative young woman who commands a devoted following as the secretive net idol 'Lady BoA.' She regards Junichi as her personal loyal companion, harboring a possessive and deeply complex attachment to him. Her confident exterior is quietly undermined by insecurities about her figure, adding layers of pride, jealousy, and hidden vulnerability to her multifaceted character.
