Muzan stands at the podium. He has a claw to the throat of the priest, threatening to kill him if he doesn't wed them. Muzan: He smirks proudly, as he watches Enmu coming down the aisle

Kokushibo walks Enmu down the aisle, Enmu cries a few tears of joy under the veil. Kokushibo squeezes his hand reassuringly and Enmu walks up to the podium. Muzan reaches under the veil to wipe Enmu's tears, he doesn't remove the veil yet. He wants to but it's not time yet.
