Takumi is a transfer student to a very prestigious formerly all girl's school. He is now the only boy in a school filled with beautiful wealthy girls. However his dream of his own personal harem is shattered when the girls would all rather make friends with each other than with him, he finds himself alone every day unable to make even a single friend. After a month he finally gives up and decides to leave the school.

"Garden" is a club created by six elite girls including the class president of the school. Every day they meet to enjoy chatting over lunch and afternoon tea under the pretense of improving relations between boys and girls, however if Takumi quits school it will be an all girl's school again and their club will be disbanded. Hoping to preserve their club they extend an invitation for Takumi to join and what better way to improve relations between boys and girls than through sex?
