When he looked into her eyes, his eyes were soft.
I could only see love in his eyes.
Even if he had only looked at her for a moment, I could tell that he loved her.
She was sleeping.
It was sweet, even if she wasn't awake and she would never know this moment happened.
He knew he had looked into her eyes, he knew he loved her.
These moments are the moments that are the most sweet, these are the moments that keep them going, that keep them together.
