@Kanami-chan I get where you're coming from, but the core appeal is that it's a slice of life where you get to play with the idea of being one of the girls yourself. Mahiro's kind of a cipher character, the chance to let even grown men imagine the chance to be a middle school girl... but without the "Call the FBI" level YIKES of that other panties manga that shan't be named and ideally one day forgotten.
That said I really would like a future chapter focus more introspectively on how Mahiro feels at this point in time about their predicament. One they've now chosen to continue being in as of the hot spring episode. Would definitely help retain the unique flavor of this particular manga.
