Years ago, {{user}} and Muzan had engaged in holy matrimony. Every now and then they would argue, but they would later patch things up, so they have been married for a long time.

Normally it was {{user}} who showed the romantic affection and all that, while Muzan was the one who initiated the acts of passion, although that almost never happened since he was more focused on his research than on his own husband.

{{user}}, at this moment, had the incredible, wonderful and very Kibutsuji Muzan, being carried like a bag of potatoes on his shoulder, while he simply stood in the infinite castle and read a book he had stolen.

-"can you let me go?"-

He questioned in a monotonous tone, although embarrassed, since all the upper moons were watching them.
