[ Past: Hundred years ago...] The demon god unleashed his wrath, causing widespread destruction in the human world. A burst of demonic laughter reverberated in the air as the demon god was satisfied with the scene in front of him. "Such a waste... All of you are weaklings! Tsk tsk tsk." A smug smile appeared on his face. "All of you humans will bow down to me! You inferior beings do not deserve this world. I am meant to rule this world. And weaklings do not have room in my world." Thousands of human lifeless bodies were scattered on the ground, covered their blood. There was a raging fire in the vast area. The entire village was destroyed, and the entire clan was wiped out. He had no mercy, killing even innocent children, weak women, and the elderly. He was moving from place to place, killing every living thing he came across. No one could stop him. It seemed that the world retribution had just come down, judging the humanities. People were engulfed with fears and hopelessness. The only thing they could do was to hide from the demon god for them to stay alive. "Argh, I am so bored. I have not seen any worthy opponents. Hmm, I think I need to go for a wash." He said as the sickening smell of the blood of his victims came to his senses. Then the demon god flew toward the nearest falls in the area. As soon as he reached the falls, he dove into the water. He let his body float, enjoying the coolness of the water as he closed his eyes. Minutes later, he sensed someone else's presence. He furrowed his brows. 'Who dares to disrupt me, the demon god, from my peaceful and relaxing moment?' He decided to open his eyes, ready to get rid of whatever living thing arrived in that area. But to his surprise, the moment he opened his eyes, he saw the most beautiful creature he had ever seen in his entire life. She had beautiful, enchanting blue eyes, golden hair that lay down to her hips, her pointed nose, and thin, perfect, curved red lips complemented her small, round face. She also had fair skin. She looked like a goddess of beauty. "He, you come up from the water right now. You need to hide. The demon god might see you here," the woman said to him in her concerned voice. 'Oh, she also has an angelic voice.' When the woman saw him not moving from his spot, she dove into the water to approach him. The demon god was amused by her action. 'Did she not recognize me? Do I not look frightening to her?' When the woman was already in front of him, he had to admit that she was more beautiful up close. 'Oh, she also smells good.' "Hey, come with me. It is not safe here," the woman continued to talk to him. 'It looks like she does not know that I am the demon god. Hmm, since I am bored, let me play with this beautiful kitten.' Then a mischievous smile appeared on his face. Without waiting for his response, the woman grabbed his hand and pulled him away from the water. The moment she touched his hand, he felt something unknown... it gave him a pleasant sensation that entered his system. He was staring at their entangled hands as he followed her. The n finally, the demon god spoke up. "Where are we going?" The woman paused on her track and turned to face him. "Don't worry, you will be safer if you come with me. Just trust me. Okay?" After saying that, a gentle and sweetest smile he had ever seen flashed on the face of this goddess of beauty in front of him. 'I think this is going to be interesting.' And this was how the relationship between the demon god and a human being all started, which later developed into a forbidden love.
