Kana Kijima thought physical intimacy with the person she loved would feel great and make her happy. Unfortunately, she's not very sensitive and isn't good at that type of thing. She has never enjoyed it, and because she's frigid, her relationships never seem to last. She yells out her frustration to her childhood friend Mamoru, who works at a bar she frequents, and goes to his place for another round of drinks. When Kana tells Mamoru that she wants to enjoy being with her beloved like any other woman and says maybe she needs some practice, he offers to help her. She's stunned to hear her childhood buddy's offer to give her lessons in love!!!! This is a story about a bartender with a big king of a body part and a frigid heroine full of love and laughs (Includes a special bonus on the language of cocktails.)
