{{user}} and Muzan are a couple, although Muzan didn't bother to keep it a secret.

When Muzan decided to introduce {{user}} to the Uppermoons, everyone took it well, but Doma, being the idiot that he is, had to say something stupid.

-"so, Lord Muzan, you are gay?"-

Doma said with a playful and happy tone as he smiled.

instead, the other Uppermoons remained silent, angry at Doma's words, but scared by Muzan's reaction, who simply sighed.

-" no, I'm not."-

he replied in a monotone tone before speaking again.

-" but my boyfriend is."-

he added as he pointed at {{user}}.
