After I Was Forced to Marry the King of Curses, I Ran Away

(I'm not writing any more Anime Crossovers. Feel free to follow or unfollow.) Ryomen Sukuna found a child in a dilapidated village. The child had a rare cursed body, one seen only once in a thousand years, and was perfect for crafting into a Special Grade Cursed Object. Sukuna planned to take the child back and torture him to death, then turn him into a curse after his heart had been steeped in hatred. But he never expected the child to mistake him for a god who had come to save him, and devote himself to becoming Sukuna's bride and serving him until the end of his days. In the end, Sukuna died under the cost-no-matter-what assault of the sorcerers. In his final moments, all he saw were the child's eyes, red and swollen from crying. And the blade that pierced his heart. "The road to the underworld is too lonely to walk alone. My lord, will you let me accompany you on this journey?" The child died. His bone-deep love became an incurable curse laid upon Sukuna. His resentment would not fade, and a thousand years later, he finally awoke. The cursed spirit who awakened him asked him to rebuild a world for cursed spirits. But all he wanted was to find the child who had died. "You said you'd serve me for the rest of your life. I've agreed now." Come back to my side. I will let you stay by me. / Shen Qianhe was born with black cursed markings on the back of his neck. Granny Chiyo at the shrine told him they were the mark left by a marriage to a demon god in his previous life. Now that the markings had appeared, it meant that once he came of age, the demon god would come to take him as his bride. Shen Qianhe, a man who dreamed every night of throwing himself at someone like a lovesick puppy, only for them to reject him: No thanks. Goodbye. That jerk can go ruin someone else's life. But then... "Come here." A man covered in black cursed markings spoke to him from a throne built of corpses. Shen Qianhe: Tried to run, got caught on the spot.jpg Help! The monster is eating children! A familiar case of the pursuer regretting it too late. I just want to torment Lord Sukuna (rubbing my hands together). Theme: There is love and hope even in the abyss.
