The merman and the siren

chapter 1

Warning: bad English(?), Muzan being a cocky bastard, (M/n) too(?), slight yandere themes.

Key words: (m/n): male name, (h/l): hair length, (h/c): hair color, (t/c): tail color, (t/l) tail length, (s/c): skin color, (e/c): eye color.

Muzan pov:

I heard from other mermen, mermaids and staff that a new "merman" is on his way, i also heard that he's very handsome. That mostly peaked my interest, every merman and mermaid is way to low for my standards. Maybe i have too high standards, but i don't really care.

I heard his name is (M/n) or something like that, but i wanted to see how he looked, if he really was that handsome as said, then i might make him my mate. I still need to wait a few days tho.

(Time skip.)

(M/n) pov:

I was put into this strange tank, there's quite alot of seaweed and seaflowers, there are alot of rocks and seashells, which is okay i guess. However there are no fish! Like why!? Whatever. I felt eyes on me, i mean, i know how handsome i am but so many humans 
looking at me makes me annoyed. I didn't only feel humans look at me...there was a certain merman looking at me.

I decided to look at the merman and holy shit...he's so fucking handsome! I mean just look at him!

He has long, white hair, red marks on his stomach, arms and forehead, red crimson eyes, a long, dark red tail with black tips on his fins. It made my cheeks heat up...No! I can't fall inlove with someone i don't know! Whatever.

But i'm a siren and he's a merman, i mean, it was never frowned upon that sirens and mermen or mermaids mated, but it was uncommon, but still tho...

Muzan pov:

It turns out those rumors were true, the new "merman" is very handsome, he has (h/l), (h/c) hair, smooth (s/c) skin, a (t/l), (t/c), tail, a well build chest and don't even get me started with those beautiful (e/c) eyes.

The reason i said "merman" is  because he doesn't really look like a merman, he has a slightly bigger chest then other mermen, the way he swims isn't like a merman, and ofcourse his tail end has a strange shape, a merman and mermaid tail is more like a crescent moon form, but his has more like a crescent moon with large a crack in the middle.

You can say that he may just have been born like this but...he has 9 little fins on his tail, he also has 2 little fins on each elbow, while mermen and mermaids have 6 on their tail and 1 fin on their arm. He also has slightly larger fins on his ears.

So if he isn't a merman then what is he? I don't care. He stole my heart and i'll make him my mate...

I was sure of it now, i will make him mine. My mate...mine...my one and only...
