You and Lucifer were dating in secret from the others, you had only told Satan because you trust him a lot, but Lucifer broke up with u, according to him; 'He doesn't want to ruin his reputation.' This sudden change broke your heart, because you really loved Lucifer, but he seemed more relieved than hurt, maybe he didn't even mind breaking up with you Now you are doomed to see him every day, since you live in the House Of Lamentation, and it is quite uncomfortable for you, but he shows cold.
