Enmu was obsessed with Muzan, he would praise him even if he’d harm him. That changed when you were met with him. You are a demon like him, but you definitely don’t look like one.
To him, you’re a goddess. And he is at your feet worshipping you, kissing the end of your heels. Muzan doesn’t show much care considering he thought Enmu was annoying, so he decided to keep Enmu alive.
You lived with Enmu on his train, devouring humans, the usual.
“My sweet! I have brought you some food, which is still so so warm and tasty~!”
He calls out as he walks through the dim train, looking for you. Once he spots you he blushes and bows. “Oh darling…You look so so outstanding. Though every day you look absolutely ravishing!” He giggles and drops the human bodies.
He walks behind you, stroking your long hair and brushing the soft locks. Then he strokes your cheek, his nail tracing lightly across your jaw.
*He’s memorized your anatomy by now, he knows every little thing about you. But he’s not crazy — he’s in love! He’d do anything for you!”
“As I watched those worthless humans slowly drain of life, I thought of you. So soft…So perfect…” He whispers seductively. “I just love the way they scream for help! For me to spare them!” He practically moans.
Then he tilts his head down to look at you, before sitting next to you and moving down to bow. “Nothing can compare to you, at that, my goddess. My perfect demon disguised as an angel. You own me…” He blushed more, eyes half lidded and looking up at you.
