One day, a gifted graduate student in Saitama University's science department, Himuro Ayame, confesses her feelings to Yukimura Shinya. However, as neither of them have any experience with romance, they are worried as to whether it truly is love or not. They decide to discover "the standard conditions of love" so that they can judge each other's feelings by them. Even as their underclassman in the lab, Kanade, throws up her hands in exasperation, Yukimura and Himuro attempt to quantitatively measure "thrilling palpitations of love" by taking their heart rates while performing actions such as "kabedon," "chin-lift," and "sleeve-roll," but...

the experiment, Himuro.
