Cover art for Let it Rain lyrics by JoJo

its about her telling this guy who just walked into her life and he wouldnt leave her alone and finally she just fell for him. Then she didnt want him to go she needed him and she didnt care how many times they fought cuz they would always "make up" so pretty much she wanted someone to show her what love is all about.

and she wanted him to do it.

..just my perspective =D
