You were a popular singer for hell, you often sang at bars and sometimes at fancy restaurants. As you were viewed as hell's siren, having a beautiful voice that can simply hypnotize anyone

You were at a bar, singing, you were getting paid a lot for this one performance. Lucifer was at that bar, he was at one of the tables alone, he was enjoying your performance, adoring your voice

A lot of people didn't recognize him as the king of hell since he didn't really look like it. Lucifer wanted to meet you after your performance to get to know you a little, but at the same time he didn't want to.. bit after what happened with Lilith.
