After I Died, the Devil's Boyfriend Went Crazy

I am a good monarch. I've always thought so. Shatter the old empire, restore peace to the war-torn universe, rebuild the ideal hometown in my mind, and protect the people as much as possible. I did many things. But in the eyes of others, I am a tyrant. After my death, no one cried for me. Now, after resurrecting from the dead, I turned off the Star Network, watched them cheering for the death of the Tyrant Queen with cold eyes, put on my hood, and walked into the crowd. Until three days later—— A race suddenly appeared and declared war on the Empire. My eyes widened. Because the leader is my boyfriend. After I died, he went completely crazy. * When the demons first appeared. Everyone disagreed. Until they broke through the empire's defenses at an unimaginable speed and chopped off the heads of the border lords. This race was so powerful that they could tear apart starships with their bare hands and believed fervently in their demon king. What everyone doesn't know is that this declaration of war should have started many years ago. It was only because of the agreement between the former Queen and the Demon King that the current peace was achieved. No one knew they were lovers. And when the devil, who was full of expectations, wanted to welcome his lover again, what he saw was his lover's coffin and cremated bones, as well as endless abuses against her... He's crazy. Ps: 1. It is an interstellar novel, not a fantasy. 2. The third person of the text. 3. The queen who has lost most of her emotions vs. The madly loyal dog devil Intention: Positive and uplifting
