Why Japan? Seriously. What's so appealing aobut hte "duhhh i did what now" trope when it comes to the main character having sex. "i can't remember at all" I hate it as much as the "Whoops, You didn't lock the door or something so I just walked in while you were changing, and am now unreasonably hated by one or more members of the cast!" trope. I'm not saying all tropes are bad, I'm an isekai junkie for lack of a better term--especially if its got MMO bits mixed in, but I just can't stand that bullshit man.
