Books had always been Kakei Kyoutarou’s Truth; he couldn’t hope to ever encounter anyone as pure, elemental and honest as black words on white paper. So he found companionship in books. He Befriended books. Dated books. Other people were merely obstacles that got in the way of his reading. He saw from a young age how hypocritical and false they often were. Better to get lost in books, which wouldn’t put on airs, betray or hurt him.
Kyoutarou is kind of a messed-up individual. Sure, all kinds of people loath their birthday, but to have a sepia dream about hospital staff (or something) pretending to have a fun birthday party for him when he knew they’d rather be someplace else? Frankly, treating all people as if they were like that is as silly and wrong-headed as Senri thinking Tsugumi had ulterior motives for nursing her to health.
Obviously, Kyoutarou’s time in the Library Club has switched on entirely new lights in his world, ones that have nothing to do with books. When he flags down Senri and gets her to believe Tsugumi’s intentions were good, and Senri asks him what good good intentions are, it’s a reflective moment for him. Seeing Senri run from the club mirrored the turmoil in his head regarding whether to stick with it past Golden Week, along with his past distrust of anyone and everyone’s kindness.
We say “past”, and used the past tense above, because while Kyoutarou still clings to his old reslusive bookworm persona, the reality is he is transforming into something else altogether; something far more sociable. And it’s understandably strange, frightening, and even a little fanciful feeling (the cosplay and the high level of attractiveness of his clubmates also contribute to the “too good to be true” vibe, or rather the “I’ve never felt like this before, so it must not be for me” vibe.
Sure, it’s a bit bizarre and potentially problematic that every girl in the club seems to have varying levels of feelings for Kyoutarou, as exhibited in how they react to learning Nagi’s his neighbor and has been in his room. The bathhouse segment also seemed to be little more than an opportunity for the girls to be nude, compare boob sizes, but to their credit, the guys stay on their side and don’t try to sneak a peak. Saints!
But really, that’s all pretty painless and is over relatively quickly, and the episode moves on to Kyoutarou’s choice: whether to stay with Tsugumi, the others, and the Happy Project, or go back to being alone with his books. Neither choice could necessarily be called wrong, but the latter is certainly safer and more mundane. He’d be returning to a path already well-worn…by himself.
In the end, even after all the fun and new experiences he’s had, Kyoutarou heads to the library club prepared to take that safer path anyway. “It’s been enough,” he thinks to himself, totally unprepared for a surprise birthday party, suggested and organized by everyone. In he presence of such unbridled joy, Kyoutarou’s heart stirs. It’s a feeling that’s inscrutable now, but like a good book, he wants to dive into it and continue to discover all he can about it, so he decides to stick with the club after all.
