Midou Nozomi, the heiress of the Teikoku Group, left her wealthy family years ago to support her poor boyfriend, Sano Shota, disguising herself as Mitsuta Nozomi to help him rise to become a director at a major corporation. While handing out flyers, she was found by her three devoted older brothers, who begged her to return home. But for Shota’s sake, she refused. However, upon returning home, she was shocked to find Shota cheating with a woman named Mitomi Minoru—who claimed she was the real Midou heiress.
