RikeiKoi's comedy is a bit less about shock value, and more "matter of fact" exposition. Rather than focusing primarily on moments of outstanding stupidity or clumsiness, the humor tends to explain situations in outrageously excessive detail. So for example, another romance comedy would specifically set the tone by lovers about to kiss being inconveniently interrupted by unforeseen disturbances. RikeiKoi plays this a bit differently where our main characters about to kiss are not only disturbed but specifically mention how this disturbance creates a suboptimal mood index for kissing. How much you enjoy this show will largely depend on how much you are entertained by this style of comedy.
Comedy set aside, the show has rather appealing presentation with a colorful while not too over the top art style that is easy on the eyes. With such a heavy focus on real-world science, most of the episodes devote a short segment of time explaining possibly obscure theories or vocabulary in a concise manner. While these segments could be argued as breaking the flow of the comedy, they are nonetheless informative and also help the viewer appreciate the methodology of our two science-type lovers, especially considering how often recurring many science terms are within the story. It's also somewhat impressive to study the detailed formulas and diagrams the characters use in their pursuit of quantifying love. Even if you aren't a data obsessed individual by nature, it should be apparent to the audience that the author put a lot of thought in the science, as silly as it may be.
Something I personally felt the RikeiKoi did well was present memorable characters. Aside from quality performances by both well-known voice actors as well as newer ones, every character had either an outstanding personality or catchphrase that I could identify them for. One could certainly argue that Yukimura exclaiming "never base decisions on supposition" gets predictable. I personally think it's this very predictability that lends itself to comedy that has the lightheartedness of a meme. It is both outrageous and refreshing how this character's ideals are given relevance repeatedly throughout the story in his pursuit to not only define love, but to in fact legitimately open up to his beloved Himuro.
RikeiKoi is a short and sweet romance comedy that I think the average science and math nerd should find especially interesting. And as a final note: Science-Type Fairy Tales are truly a victory for humanity and RikeiKoi should make more of them.
