It all started so innocently.
A few flipped skirts and wayward gropes at most.
You had probably been abnormally young when you started noticing girls for the first time. And as a young energetic boy of course you were curious. Its not as if anyone had specifically told you, you can't grab girl's chests,or peeping in girl's windows is bad.
Not yet anyways.
Of course that hadn't stopped you or anything. If nothing else, that made it a game. Just like sneaking out for the thrill of getting caught, or drinking because your parents said you couldn't. Plus the looks on girl's faces was always so cute, all blushing and indignant, and if you were really lucky then even a few tears.
Pair that adrenaline with the subtly pleasant ache that came with seeing the smooth curves of skin or the pale pink of lips and you was more than sold.
You were obsessed.
Naturally, in a respectful, reserved society like yours, such behavior could never stand.
Hammered into your young, impressionable head more than enough, over and over, touching girls is bad, touching girls is bad, touching girls is bad.
It didn't really stop you.
It's just now instead of being a blatant pervert, you were a closet pervert, or a kid with no concept of privacy, subtlety, or personal space in most peoples eyes. Because obviously, if you got a little too touchy feely with even guys, then it must not be a sexual thing. Obviously.
That went on for a while.
It wasn't really unpleasant or anything, just kind of boring, kind of lonely, always having to restrain yourself that little bit, so as not to give in to any unsavory urges.
Because damn it did you have urges. Sometimes it was an errant breeze toying with some girl's too short skirt. Other times it was as innocent as a tear and a blush on some poor heartbroken thing's face.
Then there was that one time in gym, when you weren't paying attention and plowed some guy clean over. Though obviously through no doing of your own, you fell on top of the kid in a rather incriminating manner, and gender be damned, that boy blushed and almost teared up, shoving you off and calling you a pervert under his breath.
And that was how you met Aoyama.
