Aww...we love you too, Ayu-sama!!
Thought of MOON in the first line....
"We looked up together at the moon that looked close enough to touch, didn't we?
It was so beautiful that I felt pain in my chest and was about to cry"
Those lyrics are even more precious to me since  she cleverly used them like that...
and 
"There's never a day where I don't forget you guys"....reminds me of something in HANABI that goes:
"There's never a day that I have
to remember you because
I never for a moment forgot you"
