Arima Teppei inherits wealth and responsibility overnight when his grandfather claims him following a tragic accident. Now enrolled at Shuuhou Gakuen, an elite academy reserved for the ultra-rich, Teppei must adjust to the expectations of corporate succession in a world where every student comes with fortune and status built in. His grandfather Isshin, a powerful figure in the Japanese economy, wants the teenager to eventually lead the Arima Group, and Teppei soon learns he has been promised in an arranged marriage to Sylvia van Hossen, who is just as wealthy as he now is. The result is a romantic comedy with plenty of ecchi touches.
