The Amami family consists of Hasaku-kun, his older sister Mao and his younger sister Airi-chan. Their parents were the founders of the Academy for the Education of Love between Students, but they died in an accident. Their dear Aunt May took over the academy and forced Big Sister Mao to resign as the founder. Her plan was to turn the academy into an elite educational institution such as Meha-kon, where girls would learn the craft of love and the ability to sell themselves to rich and wealthy men. In short, it was a kind of academy for perfect brides. Unfortunately for Aunt May, all students at the academy have to sign a charter, and since there are male students, it is not possible. May forces the girls under her control to mock the boys and force them to leave the academy. In the end, of course, almost all the guys left the academy, leaving only our main character Hassaku-kun. Auntie Mei tried to get the guy to break his contract to leave the academy, but everything was in vain, because the guy turned out to be a very tough nut. Sex and humiliation was the only thing left in the stock of a poor and exhausted aunt.
