(FINISHED) Haikyuu oneshots(lemons,fluffs,smut) And My Haikyuu Art

Oikawa x Iwaizumi (mermen au)

"Iwa-Chan~Come back!It's dangerous!Your mum and dad will kill you!"

"That's true....maybe another day."

"Trashykawa!Hurry up!And be quiet....it's night up there...don't sing,either"Iwaizumi said,his green-blue tail shimmering in the water.

"Sorry.....You still love me right,Iwa-Chan?"Oikawa said,pouting sadly.

Iwaizumi kissed Oikawa's lips gently."Yeah...now shhhh...or you'll wake everyone."

With a blushing face,Oikawa followed up after Iwaizumi to the surface.

Iwaizumi pulled himself up onto a rock,leaving part of his tail in the water.

Oikawa came and sat next to Iwaizumi,dipping part of his tail in the water.

Iwaizumi wrapped an arm around Oikawa,kissing his temple softly.

Oikawa leaned into his boyfriend's soft touch.

"It's so pretty..."Iwaizumi breathed.

Oikawa nuzzled into the side of Iwaizumi's neck.

"Yeah...what do they call that thing?...the one in the sky"Oikawa asked,pointing to the moon.

"They call it the moon....from what I've heard...a couple that are named Tsukishima and Yamaguchi.Do you really think they live there?"Iwaizumi explained.

Oikawa smiled softly and looked at the landscape of the beach and buildings.

"Do you think it's good?"Oikawa asked.

"What's good?"Iwaizumi asked,looking down to the snuggles up Oikawa.

"Having legs..."Oikawa sighed.

The couple do admit,they want to go to the surface,have legs,and walk around.

Although,to do so,they have to be of royal blood.

The royal blood receives a necklace that makes them human.

It's either that,or,really want to leave their families behind forever.

Neither of them wanted to.

"Maybe...I promise we'll be humans...in our next life...and meet again"Iwaizumi said.

Oikawa closed his eyes,swirling his cyan-dark blue tail around Iwaizumi's.

"Iwa-Chan...."Oikawa said softly,tears in his eyes"I promise too...."

"Let's go back,the sun is coming up,people will see us"Iwaizumi whispered.

Oikawa nodded,unwinding his tail from Iwaizumi's and dropping back under the water.

Iwaizumi followed.

"I knew it~"a voice sang.

The two swirled around and saw Prince Suga and his fiancé Daichi Sawamura.

"You two are so obvious"Daichi smiled.

Suga lay his head on Daichi's shoulder.

"I won't tell my father on you.I'm not like that.I will allow you to leave at night only.If anything happens.I gave you permission to do nothing,ok?"Suga said.

Iwaizumi and Oikawa nodded.

Daichi took Suga's hand.

"I'm in no place to say anything,but,if you get injured,come to me.And stay away from boats"Daichi said.

"Thank you"the two said in unison.

Suga swirled around"don't worry about it,now get some sleep."
