The forest was cool and quiet, but footsteps walking in the forest could be heard amid the noises of birds and the river. The man, in a neat but black hanbok, was the one walking, with his hands clasped behind his back as he moved through the forest, a slight devilish smile on his beautiful lips. He was walking, looking for his prey - someone whose soul he could lure and claim. He was the demon. ————- "You can't love that feeble human, you know? It's best you eliminate her, take her soul, get the book back, and quit being so feeble over that useless human." The pretty middle-aged lady scolded the young, handsome demon standing before her. "Demon mother, I've told you, my powers don't work on her no matter what. I don't even understand love, so how do you expect me to love that insignificant person? I just have to play along with her to get the book. Stop irritating me with your words. I'm leaving." The demon responded arrogantly and walked away. He's a demon who thrives on taking souls to enhance his power and longevity. Despite being born in the 2nd century, he never aged. Handsome, cold, arrogant, and powerful, he excels at tempting humans and making them fall for him completely. He lures mortals by offering them their deepest desires, only to return after fifteen years to claim their souls as payment. But how did this demon end up falling in love with a human, someone he considered insignificant? What do you think sets this human apart that made the demon fall for her? Let's uncover what twists and turns the story holds for us.
