One Shot Book {Kimetsu no Yaiba}

Muzan X Giyuu

Omegaverse au

Alpha X Alpha

I dedicate this chapter to Ahn-Jiwon and mstarmy. Welp here goes nothing-

"Ahn~"

Giyuu moan as the raven nibble on his neck,leaving a dark hickey showing everyone that the emo guys is his. He lick his lips and smirk in satisfaction at the mark he just made on the blue eyes male neck. Giyuu on the other hand grumble and slightly push the raven away.

"That's enough you he-heing bastard,you need to go home right now or else your husband/wife gonna get worried"

Yup,you read that right. The raven already married to guys name kamado Tanjirou, giyuu's best friend.

"Yeah,yeah I get it. I wish I can just end it all"

The raven grumble it out and heavily sigh as he laid his forehead on giyuu's shoulder. He wish to end it all with the red head male, he wanted to but the one who's stopping him is the emo guy himself. Saying that he doesn't want to hurt his best friend but didn't he already hurt him by cheating with his 'best friend' husband?. Seriously he don't know what's going on in his lover -soon to be husband(he wish)- mind. Suddenly his phone vibrate indicating that someone is calling him and he don't need to look at it to know whom. He sigh again for the nth time that day.

Welp looks like he need to hit the road before his 'husband' got even more worried about him.

-------------------------------------------------------------------------------------------

2 weeks has gone by since the marking-hickeys-take place. Since than muzan also spend most of his time with his secret lover and neglected his own husband at home whom always worried about him whenever the raven didn't get home pass 12 o'clock. He wouldn't sleep until he know that his husband back home or at least message him that he gonna sleep at some friend house. He been doing that a lot these few month, sleeping at a friend house I meant. He once told his best friend inosuke and zenitsu about it and they said that he might be cheati- but he didn't want to believe that. He trust the man,if not than why would he already married the man right? Yeah that's right.

"Stop lying to yourself"

He know what the voice said is true,he had been lying to himself. He actually know that the man haa been cheating on him, but with whom? he didn't know. A click of a door could be heard. Tanjirou muster up a smile on his face as he made his way to the front door,holding his stomach.

The front door open and tanjirou greet his husband with a big wide smile on his face.

"Welcome back honey"

He said still with the -fake- smile on his face. He help his husband by taking his suit case and put it aside and take of his husband coat and hang it on a nearby hanger.

"The bath is ready"

Tanjirou said and without a word the raven walk pass his still smiling husband to the bathroom to take a bath. Tanjirou stood there,in silent and a lone tears fall from his eyes socket.

"If you have someone......why didn't you just let me go?"

He mutter under his breath and wipe the tears away.

----------------------------------------------------------------------------------------------

Giyuu stare at the ceiling of his room in wonder,did he do the right thing? I mean,he's cheating with his best friend lover for f*ck sake. They even did the deed almost,every night. It uncountable with how horny the raven is.
