Science Fell in Love, So I Tried to Prove It

E1. Science-types Fell in Love, So They Tried to Analyze It.

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...

E2. Science-types Fell in Love, So They Tried Experiments.

To find proof as to whether he is "in love" or not, Yukimura pats Himuro on the head from point-blank range. Seeing this, Ibarada, an upperclassman in the Ikeda Lab, talks about the need for a control experiment. In other words, in order to prove that the racing of his heart is because of Himuro specifically and not just because he's facing a woman, Yukimura has to pat Kanade and Ibarada on the head too. Himuro, on the other hand, sets out to prove that food made with love tastes better and cooks, but...

E3. Science-types Fell in Love, So They Try Planning a Date.

When Himuro finds out that her junior in the Ikeda lab, Kosuke, has spent over 220 thousand yen on his beloved Aika and holds her every night when he goes to sleep, she is shaken by the realization that the only present she's ever given Yukimura is a notebook, and that she's never held him while she slept. She worries that she can't objectively call what she feels "love." As Yukimura and Himuro endlessly debate "love" using numbers, Kanade proposes that the two of them go on a date, but...

E4. Science-types Fell in Love, So They Tried Going on a Date.

Yukimura and Himuro wear lab coats, as befits science-types, as they get ready to begin their date experiment. Kanade is there to watch over their date and record observations, but she can't help bursting in to tell them to buy date clothes. Both of them are wearing monitors for heart rate, blood pressure, and temperature, and they're using an app to record things like "times my heart raced," "times I felt happy," "times I felt relaxed," and "times I felt uneasy." Suddenly, a man appears and starts hitting on Himuro...!?

E5. Science-types Fell in Love, So They Tried Holding a Meeting.

Today is a day when the members of the Ikeda lab gather to announce research results. When Kosuke cites Aika as an excuse for not having read the papers he was supposed to, Professor Ikeda's muscles expand and he crushes a pen to smithereens. On the other hand, Yukimura and Himuro give a joint presentation of the results from the date they went on. As they present the records stating in which situation their highest recorded heart rates were, writhing in distress with the embarrassment, Professor Ikeda's reaction is... On top of this, In order to increase the amount of experimental data, Yukimura and Kosuke, and Ibarada and Kosuke, form pairs to measure data on their vitals...

E6. Science-types Fell in Love, So They Tried Kissing.

Ibarada suggests that one of the greatest factors in the base conditions of romantic love is "whether or not you want to kiss the person," so Yukimura decides to try to kiss Himuro. However, Himuro doesn't like the idea of a kiss where the exact angle is measured with a protractor. When Himuro realizes that if the mood were more like it had been in the Ferris wheel, she might not mind a kiss, she and Yukimura create an equation to numerically define "mood value." In what location might the "mood value" be highest? And will the two of them be able to kiss...?!
