On one occasion, a woman named Mariya Hino purchased a lottery ticket on a whim and was fortunate enough to win the grand prize, resulting in her becoming a millionaire overnight. As she fantasized about how she would spend her 300 million yen fortune, she accidentally dropped her bankbook. By chance, a woman named Tenma Tsujidou retrieved her bankbook and subsequently requested that Hino become her sugar mommy in exchange for its return.
