When high school student Shinozaki confesses his feelings to the beautiful and aloof class representative, Akiho Kosaka, the last thing he expected was for her to say "yes." Like everything else in her diligent life, Kosaka takes dating quite seriously. In an effort to be a good girlfriend, Kosaka decides to meticulously study (and bluntly suggest) all manner of ways to keep Shinozaki sexually satisfied in the theoretical sense, that is. This innocently lewd relationship is only just the beginning.

Ooshiratorizawakane Himeyuriko is a super duper rich young lady. As a result of following her family precept of ``live honestly'' too thoroughly, she becomes a girl who openly and frankly tells everything she thinks about, including her romantic feelings and sexual proclivities. She falls in love at first sight with Tachibana Yui, a high school girl who has an unapproachable aura of a domineering yankee, although she expresses her feelings, all that comes out of her mouth are vulgar words. Will there ever be a time when this one-sided love will be rewarded, in which she does not give up even when she is ignored or treated with a curt attitude, and keeps her love aura at full blast?! Himeyuriko's pure love (including her sexuality) runs wild in this love comedy!
