Albus likes those mornings right after Lucy spends the night. He likes the way she looks at him with her wide round eyes, and wonders where she went wrong. When she started falling in love with him, she stopped giving him those looks, and started waking up next to him and giving him that smile that made him fall in love with her, too. He likes those mornings better, when she stays instead of leaving him with no answers between the cold wrinkled sheets. When she whispers that she might actually be in love with him instead of saying nothing at all. Yes, he decides, he likes these mornings, almost as much as he loves her.
