The following contains spoilers for Season 2, Episode 3 of Science Fell in Love, So I Tried to Prove It, now streaming on Crunchyroll.

Season 2 of Science Fell in Love continued to toy with the boundary between slice-of-life anime and the hard science of chemistry and experiments, and Episode 3 takes this in an entirely new direction. Much of Season 1 was devoted to proving the love between Himuro Ayame and Yukimura Shina, while the newest episode explores more diverse ideas of science and true happiness.

Even abstract, universal ideas such as art and human emotion can be analyzed through the lens of science and hard data, and that's exactly what the students of Saitama University do in Episode 3. Ena and Kosuke in particular put basic human happiness to the test and wait eagerly for the results. However, what they get might surprise all of them.

Season 2, Episode 3 of Science Fell in Love explores the boundary between science and happiness in two distinct ways. First, the burly professor Ikeda presents his contribution to the university's pamphlet, wishing to use the science of bodybuilding to make Saitama University more appealing to prospective students. It's true that colleges can make use of creative and memorable ideas to inspire new students to enroll, but Professor Ikeda's idea falls short in Ena's eyes.

Ena gently criticizes Ikeda for projecting too much of his own beloved hobbies onto the pamphlet, and working out is hardly relevant to Saitama University's science department anyway. Professor Ikeda feels dismayed that his idea was badly implemented, but it can still be salvaged. Fortunately for him, Ena shows her kind, caring side and writes an all-new paper on the hard science of exercise and mood, and she feels certain that this can be used by the university somehow. In fact, she feels inspired enough to try some exercises of her own, baffling Kosuke in the process.

All this helps to prove that the sharp-tongued Ena actually does have her generous side, and it says something about Ikeda too. He may be an excellent scientist and a fine bodybuilder, but he clearly struggles with expressing his ideas in a sympathetic and compelling manner. This minor, humorous weakness of his is sure to show up in future episodes of Science Fell in Love.

Later in Episode 3, Science Fell in Love tests the boundary between science and happiness in an even more compelling way. Episode 2's final scene hinted at a budding romance between Kosuke and Ena, and Episode 3 takes that to the next level when Ena reviews Kosuke's methods for finding his soulmate. Kosuke knows what he likes -- a petite, beautiful, sharp-tongued girl with frilly outfits. The problem is that the fictional Lasally Naim proves too difficult for Kosuke to unlock in his favorite mobile game, and his statistical approach is all wrong. He won't find true happiness this way.

Ena corrects Kosuke on his math, then uses the Drake equation to determine how many Japanese women will fit Kosuke's strict criteria. To Ena's deep amusement, the final result is lower than one, and she can barely get it above this number even with less strict parameters. Kosuke nearly gives in to despair until he realizes that if there is just one Japanese woman who fits his criteria, then Ena, who stands before him, could be that woman after all. She fits the parameters exactly, and the math says that she must exist. And she certainly does.

Kosuke remains too shy and flustered to speak up about this, and it's likely he hasn't yet come to terms with his budding amorous feelings for Ena. This is a challenge that should keep Kosuke occupied for the next few episodes of Science Fell in Love, and whatever he says or does about it will reveal a lot about him. The same might also be true of Ena, who at least finds Kosuke funny and cares for his well-being. So far, it doesn't seem that she has a serious crush just yet, but she did blush a little at Kosuke's amusing behavior. The seeds of romance might already be planted in Ena's mind, and it's up to Kosuke to water them. They are sure to find happiness in each other's arms before long, and best of all, the math checks out. It's destined to be.
