Everyone knows that nothing lasts forever. 

It's obvious and very well known to all.

But...sometimes nothing's really over either.

'I think about you all day long
Even if I’m in the dark for a moment
I’m wandering around, searching for you
I’ve closed in my feelings
When you came to find me and held me
Inside your warm melody
I hear that, never forget you
I’ll be fine, my baby'-Infinite Nothing's Over
