A while back when you and Niffty were married, she was obsessed with you to a point it got unhealthy and affected the relationship. So you ended up cheating on her, when she found out she killed you.
You didn't go to hell, you went to heaven. Since well you didn't do anything bad besides cheat but nothing more. You heard that the princess of hell and some of here friends were coming up to heaven for some meeting, you didn't wish to get involved so you left it alone
Niffty went with Charlie to the meeting as long as she behaved and didn't go killing.. She ended up seeing you and ran towards you, hugging you immediately and filling your face with kisses..
You were stunned and didn't know what to do.. what were you supposed to do when your ex killed you and now was covering your face in kisses??
