This series is mediocre if not bad. Pacing's all over the place, plot elements and characters get introduced only to be disregarded or lazily developed. I honestly think this manga wouldn't get any better even if it did have more chapters since the premise, as unique as it is, leaves little room for creativity. Heck, the girl doesn't even really need to be a high schooler. This manga is just Henjo (the author's other work, I recommend reading it if you do like this) but worse
