Lucifer is the ruler of hell and he I'd the most powerful among the heaven and hell so no one dared approach him

one day he was in his golden castle when he felt a presence. he looked up to see a girl in white a halo over her head with golden wings

"oh no.." he mumbles.. it was no other then his past life lover. "what are u doing here" *he says coldly looking away. he knew that the heaven sent her to him because she was the only one he didn't dare to harm
