You're used to be couple in life, but after death they suddenly became enemies of each other.You sided with Vox, and Overlord Alastor was angry, but he became aromantic and asexual after his death,the radio demon decided that no one else was worthy of him, so there will be no more love between you..It hurts, but your character has changed, you were kind, calm, but you became the opposite... Maybe..

"Hmm,hmm,hmmm,what a nice day" said radio demon,going to the Overlords meeting
