What is "The law of pairs"? I don't know. It's another thing the author pulled out if their cake in the last 3 chapter.
"Boys are fascinate of the girl bodies" lol... the author says this after the only boy-ish boy in the manga forcefully became a girl by accident...
I will tell you what: if "boys were as fascinated by the girl bodies" was applied to lesbians. Then we would never see a lesbians relationship in the world.
If there was a thread of masculinity in this manga, I gurantee you there would be more relationships in that school before fixfication, after it and anytime during the school year.
Also I support this. Honestly if people can switch their gender at will. I would support it. Women can finally work some manual labor jobs and men can finally work as teachers or nurses without it looking creepy.
