That's why I'm so hung up on this story. If Mimika had the same character, performed the same, and simply had her gender flipped, I would still think it's a good story. I probably wouldn't be as interested in the story, but I'd still support his relationship with Mimika as it stands now. But that support would crumble the moment he crosses the line, and I put the same onus on female Mimika.
it gets me that a lot of people rooting for the story as it is would never give boy!Mimika nearly as much sympathy.
I know that I definitely wouldn't give boy!Mimika anywhere near as much sympathy as I give actual!Mimika, but I do have to (reluctantly) agree that the story would still be just as good. I would not touch such a story with a ten-foot pole, but I would probably think of it as a good story if I ever decided to read it. I think it's kind of similar to Kodomo no Jikan. Now, I've never read/watched that horrible thing and I never will, but, from what I hear, it actually is a pretty realistic take on... pedophilic relationships... now, assuming that's correct, I am still never going to read it just because the protagonist is a dude. I mean, even if she was female... but, I mean, I guess I did read Hoshikawa Ginza District without any hesitation so I guess I wouldn't.
As for that whole issue of "crossing the line..." I can't say that I feel the same, really. I would certainly be disgusted to a certain extent if actual!Mimika crossed the line, but if male!Mimika did that, I would drop the series then and there. If actual!Mimika did that, I'd most likely continue onward and still support her. Is that wrong? Probably, but, well, at least I can acknowledge that I'm pretty irrational and hypocritical. If this were a real-life relationship, I would definitely not support it under any circumstances, but since it's fictional, well, I guess I would regardless of the circumstances. Not really sure how I started to think this way, but I suppose it is how it is.
