Meh. I understand creating an original story is not always easy but this, this has been so overdone. I can't help but frown and even get slightly irritated when i read these clichéd scenarios
Immature girl is immature, but the worry is, immature girl grows up straight. Mature girl should gird her loins now and resolve not to moon after immature girl forever.
All this is missing is Airhead-chan rolling around on her bed thinking "OMG, my heart was pounding so much! It would've been awesome if she actually meant it!"
