Exactly. But I did wish for a few moments that Ryuoh was a bit older, like 15, and she was a bit younger, like 19. Just so that it could turn into romance.
But as long as she doesn't reciprocate, I can't see a reason for this to be creepy at all. Just plain cute. Tho I did read a manga where a 28 years old woman met a 12,13 years old boy. They began as friends and when he was 14, became a couple. He was 14 and she was almost 30. That was creepy.
Idk why people find this creepy. Most kids have a crush on people older than them at one point. You see it all the time. You know when a little kid asks a pretty girl to be their gf and all. I remember one time my friend was babysitting this kid, he was like 6 or something, and he said he thought she was a fairy and asked her to be his gf (it was so fucking cute lol) It's not like the otaku girl even likes him back anyways lol. If she did that would be yella weird but she doesn't so what's the problem
