I'm speechless, absolutely speechless.
I never knew that a One Punch Man parodie manga can be this interesting (I'm a sucker for a proper wholesome romance that's why it felt really nice and interesting but otherwise someone might get offended because of the same romance that I liked).
Ooh, but if you wanna say, you could even say that someone wrote a romance story of a cyborg and a human and then he realises that it would kinda fit the setting if genis were a girl.
So I just feel that the author just wanted to show us his romance story and the best way was to make it a parody of some sort and for this one i don't think it was a bad idea. So good job bro.
