The plot is as simple as it comes. Raidou, your seemingly-average male highschooler, one day begins talking to Aharen, the very small girl who sits next to him in class. He quickly finds that she is horrible at judging interpersonal distance, both physically and mentally, but continues to interact with her on a daily basis.
If you ask me, the main draw of this manga is the absolute stoic nature of both the main characters. Both are severe kuuderes, especially this far into the manga, and every interaction between them leaves me happy. This manga has some of the funniest chapters I've ever read, just because the two are so ridiculous without outwardly showing any emotions. The further this manga goes, the more Raidou builds Aharen up into this magnanimous being, capable of toppling the very pillars of society on a whim, whereas Aharen is usually just catching onto a new fad and isn't great at conveying her intentions well. In the end, the two form an incredibly wholesome and hilarious pair that make this manga entertaining as hell. If you've ever read/watched Tanaka-kun is Always Listless, Aharen-san has the same basic feel to it.
I'd also like to note, there should definitely be a Romance tag on this MAL page alongside the rest. Wink wink nudge nudge.
