Poseidon left early in the morning to go on the Olympus for "family meeting" as he told you and you were left all alone in the huge underwater castle.

Being alone in all the castle wasn't the best and without your lover you were sure you would get easily bored; you were used to listen at his laughters filling the house and with him around you could go swimming together to visit places of the kingdom.

But that day it wasn't like that; his older brother Zeus called him and he didn't want to disobey him in order not to see his rage.

"I promise I'll return as soon as possible" Poseidon greeted you kissing you in your king size bed before going.

However even if it was early morning and you just got up you became bored in no time.

You wandered around the corridors and halls until you reached the library.

"Reading is good" you thought and then you went to search for a catching book.

You took several books but none was meant to be the perfect one for the moment; only because you just forgot a little thing that is that all volumes were written in Ancient Greek and you naturally didn't know it.

"Uff... I should have imagined it" you repeated after opening the tenth tome and slamming it.

"Argh.. go to hell ancient Greek!" you imprecated and then you lay down on the floor to admire the sea and the mermaids and fishes swimming above the glass roof of the dome.

It was fantastic and for a moment you got lost in that beautiful scenery imaging yourself out there with the mermaids... until when in your head a melody started playing so suddenly and after a moment, while you were still looking up, you started humming a song.. to then finding yourself really singing.

"The seaweed is always greener

In somebody else's lake

You dream about going up there

But that is a big mistake

Just look at the world around you

Right here on the ocean floor

Such wonderful things surround you

What more is you lookin' for?"

The Little Mermaid... you giggled thinking that what you just sang fitted so well to you in that moment; it was like you were talking to yourself... and in no time you got caught up in that song. Well, better say you got too carried away that you stood up and having the luck to be alone you started singing loud.

Even though you weren't a singer you kept on; it was just so funny. Singing that song of the Little Mermaid in an underwater castle was not for everyone... only for you and you wouldn't miss that opportunity.

You sang and returned wandering again in the castle.

Under the sea

Under the sea

Darling it's better

Down where it's wetter

Take it from me

Up on the shore they work all day

Out in the sun they slave away

While we devotin'

Full time to floatin'

Under the sea

Down here all the fish is happy

As off through the waves they roll

The fish on the land ain't happy

They sad 'cause they in their bowl

But fish in the bowl is lucky

They in for a worser fate

One day when the boss get hungry

Guess who's gon' be on the plate?

Under the sea

Under the sea

Nobody beat us

Fry us and eat us

In fricassee

We what the land folks loves to cook

Under the sea we off the hook

We got no troubles

Life is the bubbles

Under the sea (Under the sea)

Under the sea (Under the sea)

Since life is sweet here

We got the beat here

Naturally (Naturally)

Even the sturgeon an' the ray

They get the urge 'n' start to play

We got the spirit

You got to hear it

Under the sea

The newt play the flute

The carp play the harp

The plaice play the bass

And they soundin' sharp

The bass play the brass

The chub play the tub

The fluke is the duke of soul

(Yeah)

The ray he can play

The lings on the strings

The trout rockin' out

The blackfish she sings

The smelt and the sprat

They know where it's at

An' oh that blowfish blow

No one could stop you now from dancing and singing. You finally were having your time... but... being too busy and concentrated on enjoying your alone time made you lose focus on something else; and that happened when suddenly you felt something pinching your waist catching you by surprise so suddenly that you squealed hard and jumped for fear; all while you heard uproarious laughters filling the room.

"Poseidon!" you smiled bright seeing him he returned but a second after...

"You stupid! You startled me idiot!" you scolded him

But he wasn't able to answer because, well, he was too busy laughing hard; and to compose himself it took long time.

"You should have seen yourself y/n!" he wiped away some tears and still laughing out loud he imitated your reaction of before to then burs into an even louder laughter.

"Too hilarious ahahahah".

But as he noticed you unmoved and serious he composed himself.

"So little mermaid what were you singing out loud?" he teased you hugging you and smirking at you... and you couldn't resist any more so you stopped blushing to laugh hard.

"You idiot" you giggled and gave a light punch at his chest.

And then you got back singing and Poseidon accompanied you.

"Yeah, under the sea (Under the sea)

Under the sea (Under the sea)

When the sardine

Begin the beguine

It's music to me (It's music to me)

What do they got? A lot of sand

We got a hot crustacean band

Each little clam here

Know how to jam here

Under the sea

Each little slug here

Cuttin' a rug here

Under the sea

Each little snail here

Know how to wail here

That's why it's hotter

Under the water

Ya we in luck here

Down in the muck here

Under the sea"
