"When you fall again, i won't let you fall, let me defy the gravity." 

First chances my only work for a while, and everything would broke down. A second chance would be relieving. But, once you fall, don't let others fall with you. But, defy the gravity. 
The girl whom broke down because of herself faces her weakness once again. If her world broke down, would he be the one that will defy her gravity?
