and when the daylight lyrics

The stars are burning out. Somebody slow it down. This is way too hard. 'Cause I know when the sun comes up. I will leave, this is my last glance. That will soon be a memory. And when the daylight comes I'll have to go. But tonight, I'm gonna hold you so close. 'Cause in the daylight we'll be on our own. line without a hook lyrics meaning
