The Years I Spent Raising the Scrap Boss

*The story is complete. Welcome aboard! [Thank you, lovely readers, for supporting the official version! Bang, bang, head-bonk.jpg] Yuan Yayi was a curse born from humanity's negative emotions. Nothing good had happened to him since the day he was born. The one thing he could be grateful for was that, unlike his peers, he was refined and handsome. After waiting decades and successfully outliving his "guardian," Yuan Yayi, unable to change his nature, finally let loose and began enjoying a carefree life of fighting by day and wandering around at night. One dark and windy night, while riding an ox-drawn carriage on a nocturnal outing, Yuan Yayi happened to hear a sickly human child, bedridden for a long time, praying fervently before a shrine. The child begged the gods to cure his illness and grant him a long life. Yuan Yayi: Hey! This is interesting. I've got a job to do!! A god? He certainly wasn't the sort of being who looked radiant and glorious. A "demon" made of piled-up negative emotions, dressed in immaculate white priestly robes, descended as lightly as the moon god and gently lifted the cold, pale face of the young human. "I have heard your prayer." Muzan: "!!!" After being thoroughly deceived and abandoned by a creature pretending to be a god, Muzan searched for hundreds of years without ever managing to drag the fellow out and chop him to pieces. Yet just as a swordsman cut him into thousands of fragments, that "moon god" descended once more, just as he had the first time. "How pitiful, Muzan! I heard your prayer!" Muzan curled up his tattered scraps of flesh in misery. How could he... How could he let this thing see him in this state? He should be biting hard into the side of the other's neck with his sharp fangs, cruelly raking the other's skin with his sharp nails. #What should I do about my appearance if I run into my former crush?# As the title says, I ran into my former crush, but accidentally got smashed to pieces. How can I look perfect in such a short time? Onlooker No. 1: You're in that state and still worried about your appearance? Seriously, I'm crying! Onlooker No. 2: To be fair, a person... no, a ghost, at the very least shouldn't be... (?ω?) Still confused.jpg Onlooker No. 3: At the very least, you shouldn't be a pile of pieces. Just helping the person above out. Onlooker No. 4: As far as I know, the OP was cruelly abandoned by their crush after being led on, but still secretly loves them. So even in pieces, wanting to pursue love is only natural. [Reading Guide] 1. The timeline of this crossover world is jumbled. Adjustments may be made as needed for the story. 2. The CP is set: Muzan! Aside from the canon pairing, this is the only CP. All other relationships are familial or platonic. 3. Main character is seme, no role reversal. Muzan's personality is just as nasty as in the original. Don't expect too much from him. Everyone has different squicks, so run if you see something that bothers you! 4. I like planting foreshadowing early. Anything that seems unreasonable will be explained later or in the author's notes. The story may contain all kinds of melodrama. I want to torment Muzan in every possible way. I'm a lowbrow person and I love writing this stuff! 5. Extensive headcanons. OOC warning!!! 6. All good-faith corrections are welcome. Let's all get along! 7. The author is hopeless at writing romance, so there are definitely things that could be improved. I'm working on it... 8.
