@slypy Seriously. Why are there so many people like you?
Let's see here. Teenage boy, probably a virgin, average looking. Approached by a hot girl dressed mostly like a gyaru/slut. She keeps teasing him, whispering in his ear, then leaving him hanging.
If you think the OBVIOUS take away here is 'she likes me!'...boy do you have issues. The obvious take away is 'she's messing with me'.
The time to pull the pigtails of the girl you like is grade school, not high school. If you like someone, you approach them and say "I like you". Bam. Solved.
I get that teenagers are awkward, and it's not easy to confess. But if you wanna play this card for "it's not easy to confess", then it's also valid for "it's not easy to realize that someone is into you".
