Umm, just a small thing. I know yaoi is not so close to actual realitionships between gay/bisexual men but usually when it comes to positions.. Well, you can really love him but you simply can't be the bottm, because you won't get turned on taking it up your ass. Some guys won't get turned on without having something in their ass either. It's very tricky, and usually you can't be both. You either get turned on by sticking it up someone's ass or you let someone stick it up there. I know this issue with Heiji was more about his pride, since he simply couldn't let this cute little thing top him.
I agree
i think if heiji really loved nanase, he would be okay with switching, knowing that nanase wanted to know what that felt like, too. heiji's kind of selfish. there are probably guys who like being one or the other, but i'm sure that's established in the beginning where either can voice their concerns. why does nanase keep succumbing to heiji? i know that he does it, cos he feels at ease, is in love, etc., but in reality, that relationship probably wouldn't last long.
