Some guys would think that their lovers would be an angel fallen from the sky - the angel with wings so soft, so bright with the halo that decorated her head captures their attention. Guys even see her as a guardian spirit who manifests goodness, purity, and selflessness.
 

The others would say that their lovers are goddesses who have been worshipped by the guys themselves. The goddess with grace and beauty would even shine brightly than the sun that would shame their radiance – they would truly melt at this.
 

But to Chanyeol’s, his girl isn’t the angel nor the goddess which everyone voices.

heav·en  (hvn) n.

1. The sky or universe as seen from the earth; the firmament.
    

To Chanyeol’s definition of Heaven, Heaven is the girl herself. Whenever he’s with her, he feels this paradise feeling even on earth.
 

But even though she’s Heaven herself, Chanyeol will protect her. It’s like, a vulnerable angel shielding the properties of his sky.
 

Even if  something bad will happen, he'll sacrifice everything for the paradise. And even if Heaven finds her own happiness, he'll be happy for her even if it breaks his heart.

"Your life is in danger, Heaven. I'll be your angel starting from now on..." 

"...I'm never Heaven, and I deserve to die."
