It was the way he touched her.
It was the gentle brushes of his fingers as he settled her hair behind her ears. It was the way he would brush his thumb across her cheek as he smiled her. The way he would hold her to his chest as they watched the sun set. It was the way he would brush his mouth against hers in a chaste kiss.
It was the way he would treat her. It was as if she was the only thing that ever occupied his mind. It was the way she would find fresh flowers every morning with her breakfast and he couldn't be there. It was the way he would make her breakfast in bed on Saturdays and Sundays.
It was the way he grinned at her, a smile meant only for her. It was the way he looked at her when he thought she wasn't looking. It was the way he would smile whenever he spoke about her. It was the way his face would light up like she was his world, like she meant more to him than the gold he had in Gringotts.
It was the way he talked about her. There was no better person out there. No better one to receive his love. His words could be bottled as liquid love. It was the way he talked to her. It was the words of praise, desire, acknowledgement and love. It was the way he understood her. It was the way he could make all her pain disappear simply because she knew he was there.
It was the way he would stay no matter what. It was the way he would hold her when she wanted to run away from him. It was the way he refused to let her go to sleep angry. It was the way he made her laugh merely because he could. It was the way he would massage her feet when she hadn't even asked him to. It was the way that he never seemed to tire of her. It was the way he would grab her and swing around if he hadn't seen her in a while. It was the way he would whisper in her ear, so only she could hear.
It was the moments he spent away from home, but still found time to contact her. It was the way he would surprise. It was the way he filled her dreams and thoughts. It was the way he would ask for her opinion whenever she was quiet. It was the way he would smirk seductively to get her to go with him. It was the way he would smirk when he was right. It was the way he would hold her simply because he could, and didn't need a reason.
It was the way he would write her a love letter. It was the way he would make sure she was happy, even though he wasn't.
It was the way he loved her that made her knees grow weak and her heart beating wildly.
