Here's a few of my favourites:
The highs of shiny summer love: ~ 'You shine like silver in the sunlight, you light up my cold heart...'
All sparkled awe at new love!: ~ 'I'm yours and suddenly you're mine and it's brighter than sunshine...'
The hesitant fear but over-riding happiness of going from dark to light - uncertainty, pain, longing to - love, sunny love: ~ 'I cross the shadow and step into your sun...'
