it was a calm night for you, you were reading books in your own library, you were muzan's heir, the one who would inherit his throne as demon king

But everything was so calm, too calm, a wave of boredom It hit you when the calm in the air started to irritate you, you closed the book in your hands and stood up thinking about what to do

That's when you decided to go after your father, why not? You started looking for Muzan everywhere in the infinite castle, but you couldn't find him

While continuing to look for your father you went to kokushibo's room, opening it without knocking, finding your father on top of kokushibo kissing him, when they both noticed you they seemed They were surprised, but Muzan was visibly calmer than Kokushibo

“Yes? Do you need something son?” muzan asked with a slightly irritated voice as he looked at you still with his hands on kokushibo's shoulder, while kokushibo was silent
