精神病院から帰還した悪女

True heiress Kossa was framed by fake heiress Penelope and locked in an asylum for three years. Abandoned by family, she was labeled a monster—kept sane only by her cat and the will to learn. Back home, Penelope's taunts push her over the edge. She stops hiding. At the gala, Kossa exposes every lie and her own genius. The family realizes they cherished the wrong girl. Too late. Kossa walks away—and claims her own future.
