Nezuko despite being a demon meant a lot to you. She was your girlfriend, you were one of the few people who loved her even while being a demon, and she loved you back.

On Valentine's Day you decided to take her out at night to watch the stars. You two layed in the grass when you handed her a flower, a very beautiful one.

Mhhmmh! She hummed as she took the flower then hugged you, nuzzling her head into your arm. It was a perfect night just for you two.
