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...
At any rate, it looks like there's no 
denying Himuro-senpai's heart was racing!
على أية حال، لا يمكن إنكار ارتفاع معدّل
 !نبضات قلب هيمورو-سينباي
Zumindest ist wohl verifiziert,
dass Himuros Herz rast.
Pero parece que no hay duda
de que su corazón se aceleraba.
Pero parece que no hay duda
de que su corazón se aceleraba.
En tout cas, une chose est sûre :
ton cœur battait la chamade !
Ad ogni modo, pare che non si possa negare
che Himuro-senpai aveva il batticuore!
De qualquer forma, não há dúvidas de que
o coração da Himuro-senpai acelerou!
Так или иначе, но очевидно, 
что сердце Химуро бешено колотилось!
