Back Before the Demon King Destroyed the World

[Sickly demon bottom vs. angelic, saintly top] Top's perspective: The Demon King Mo Wen was violent by nature, an evil seed from birth who treated human lives like weeds. He turned the entire continent into a living hell, and no one in the world could stand against him. The angel Ai Wei's mission was to travel back a hundred years, to when Mo Wen was still a child and his magic had yet to awaken, and kill the young Demon King. But when Ai Wei found Mo Wen on the verge of death in a shadowy alley that blocked out the sky, he couldn't bring himself to do it. He changed his mind at the last moment, took the sickly Mo Wen home, taught him right from wrong, raised him, and guided him toward the right path. But after Mo Wen came of age, Ai Wei realized that he had developed feelings he shouldn't have. Just as he was struggling with the painful realization... Mo Wen disappeared. Bottom's perspective: Mo Wen had no parents from the day he was born. He wandered the streets, endured scorn, and barely managed to survive. Then one day, a great philanthropist named Ai Wei came to town. Not only did he not look down on Mo Wen, he even took him home, protected him, and carefully raised him. Mo Wen thought life would always be happy and carefree. Until one day, in an attic no one had visited for ages, he found a worn-out notebook. It was filled with Ai Wei's bold, powerful handwriting, and four words stood out clearly on the page. Kill Mo Wen. Notes: 1. The top raises the bottom. 2. Angels and demons in a modern setting. The premise has changed from the previous version. Please remove it from your collection if that bothers you. Sorry! Theme: World peace
