There is always a risk: everything is going so well and good, but then it becomes awkward. All at once she notices you looking at her, and never wants you to joke you didn't think that she's flirting because he doesn't want you to think she likes me. It's just a disaster when someone starts to erode the wall separating friendship and kisses. And when this wall collapses, the story could have a happy mid - Oh, look, the wall came down, I saw you as a girl, and you in me - boy, and now we're going to play a fun game called "can I lay here hand in here, and here, and here?". And sometimes it is so cool that it seems to last forever. But the middle is not the end.
