Kazuma was your husband.

you were sweeping the floor of the kitchen since Kazuma now was tired from work and he usually does it after coming home.

he was approaching the kitchen to grab something, until from the door he heard some faint sound of a melody.

he placed his ear on the door and heard your voice singing quietly a soothing and calming song (you decide wich).

your voice was sending him shivers down his spine.

for him, you sounded like an angel.

he continued to listen quietly at the door.
