@Jaguar-Wing A: We have muzan be ✨furious✨ that they found each other, and just kinda give them the hardest assignments and keep them as far away from each other as possible so they fall out of love and are filled with rage and fight more cause he is stupid and does not realize that's gonna make it worse. B. We have Muzan find out and take away both of their memories, and then makes them think they're enemies and basically hate each other. Then we have them both die fighting, and then they meet in modern times and make them "finally" be able to be with each other as humans, but yk we'll throw obstacles their way because yk we love them and want their lives to be as horrible as possible✨✨✨ C. We have Yushiro ✨die✨ and now it's Mina's turn to be a depresso espresso, and have him come back as a slayer and be trying to kill her. She just kinda teases him and makes him hate her even more, but then they (oughcoughyushirocoughcough) eventually become friends and then bam! ✨perfect life✨ (but not for long cause we'll throw something else their way ofc~ if you have other ideas lmk-
