Help her up, don't let her know.

You walk over to her quickly, apologizing for the mishap, and offering your hand to help her up. She looks up, a bit upset, but seeing how nice you were she accepts your hand, and you help her to her feet. In this instance, she notices her top's mishap and turns to the side of you, fixing it with lightning reflexes, and turning back.
"Sorry about that." You say, trying to ease the whole situation with a smile
"Don't worry about it, I wasn't paying attention, should've seen you coming." She replies, giving you a warm smile.

You begin to talk for a few minutes, staying in that hallway, but going off to the side to allow others through. You find out her name is Kyrie, and she's a senior as well. She had just moved here this year, so you didn't recognize her from before. As the bell rings, you look up and sigh.
"Oh well, time's up. I'll see you around?" You say, another one of your trademark smiles comes across. She scoffs and puts her hand out,
"Gimme your planner." You don't hesitate as you place your agenda book in her hand. She pulls it up and turns to a page, taking out her pencil and writing something down, handing it back to you. It's got her number, seems you made a pretty good impression, especially considering how things started out.
"Don't be shy, text me sometime." She said,waving goodbye and heading in the opposite direction.

You turn and smile, things are going well for you so far, already a cute girl has given you her number, but now it's time for class, prepare for boredom in 5...4...
