I had some ideas so why not? :)

Author POV
After just hugging for 30 minutes, Jimin decided to cook something. While cooking, Jungkook was standing silently beside Jimin.

He didn't really know how to start a conversation with him so he just stand there, observing Jimin cooking.

"You know you can talk right?" Jimin said, not looking at Jungkook.

"Ah...right....I'm sorry" Jungkook said, rubbing the back of his neck.

"What are you sorry for?" Jimin finally look at Jungkook which made him a little surprised.

"I-I..."

"*sigh* Dinner is ready so sit down Jungkook"

Jungkook could only nod. God that was embarrassing....

They ate quietly and Jungkook notice something and it made him sad.

"H-Hey Jimin?"

"What?"

"D-Did you forget to wear our w-wedding ring?"

Jimin stared at him and simply said "Why should I? Didn't we get a divorce?"

Jungkook almost choke at Jimin's word. "We...we're not married? But...didn't we just hug and said I love you to each other? I thought you forgive me?"

Jimin sigh and decided to throw away his food and wash his plates.
"I forgive you but I don't trust you anymore, so why should I wear the ring when it's all just full of lies?"

"No....Jimin..." Jungkook says and grab Jimin's wrist, spinning him around.

"I'm sorry baby-"

"Don't call me that" Jimin snapped.

Jungkook eyes was brimming with tears. I lost him...I broke him...he doesn't love me anymore....

"Jimin...I'm really sorry....please believe me when I say this... I'm sorry and I love you so much" Jungkook said, hugging him tightly.

But all Jimin could here is- lies, Lies, LIES.

"No you don't."

Jimin push Jungkook and glare at him.

"And you never did"

Next day

It was definitely different than any other mornings they had before. Usually, Jimin would prepare breakfast and wait for Jungkook to come down and eat with him. Even though Jimin already knew Jungkook would just push him away anyway. But he still hope...

But their divoced now and the tables have turned.

Jimin now hates cooking, hates cleaning, hates smiling and most importantly,

He hates Jungkook

"I don't want to keep pretending that I'm fine jungkook, I never was...but I still kept smiling and what do I get? nothing but hate and disgust is what you gave to me" Jimin said, almost wanting to tear up. Jungkook too. 

"Hyung....I know sorry isn't gonna fix this but...please give me a chance hyung...." Jungkook said. He walk towards Jimin and hold his hand. 

"I miss you hyung....yes I treat you so bad and I regret it so much but....I don't know...I don't even know why I act that way..."

"That's because you don't love me..."

"NO! That's a lie! I really do love you! I just...."

"Just what?" Jimin said, growing impatient when Jungkook wasn't finish. Jungkook hold Jimin's hand even tighter and look at him.

"I just didn't know how to love you...."

Jimin scoff and said "And by telling me how ugly, fat and unworthy to love is how your way of saying you LOVE ME?!"

Jungkook flinch a little but he doesn't want to give up yet. I can't let go of him yet...

"Hyung please...listen to me..." Jungkook said desperately. But Jimin was starting to get angry.
"No Jungkook, I just can't okay? I left because you don't love me, I left because I couldn't take it anymore, I left because I just can't keep faking that I enjoy being with you....I just can't....I'm sorry...."

Jimin push Jungkook hand away and went upstairs, going back to his sleep.
And Jungkook couldn't help but felt guilty all over again.

What am I gonna do now?

Next day
It was Jungkook's turn to be in Jimin's position. He made breakfast and wait for Jimin to come down. And if Jimin didn't come down then he would go upstairs and bring the food to Jimin.

Even though Jimin was trying hard to denied it, but he does admit that it was sweet for Jungkook to do this.
Even if it's full of lies.

And when Jungkook is out to work, Jungkook would always put sticky notes on the bathroom mirror for Jimin to see.

Jimin would immediately smile after that. How sweet...

The notes were all filled with sweet and cheesy stuff.

Good morning hyung! I hope you are being the angel you are right now. I love you :)
-Kookie.

Jiminie hyung~ Did you get the flowers I got for you? Well, you better not throw it away okay? Those flowers bloom when they see the sunshine coming out. And it's you sunshine ;)
-Kookie

Hyung have I ever told how beautiful, perfect, handsome, cute, talented you are? No? Well now you know ;)
-Kookie

Are you a camera? Because when I look at you I just can't seem to take my eyes of you ;)
-Kookie

Hyung I really do love you and I'm changing just for you. I love you hyung :)
-Kookie

Jimin was blushing so hard every time. "He's so cheesy....not that I'm complaining...."

Maybe he isn't lying....

Soon, their relationship is getting better. They talk more, cuddle more, acting all lovey dovey and even kissing. Just the cheek.

But Jimin was not totally convinced by Jungkook's sweet action.

Jungkook wasn't mad.

I deserve it anyway...

That night, when Jimin was fast asleep, Jungkook would come to the bed just to stare at Jimin's face. That was the only time he gets to just stare at his lover face.

"Jiminie....when will you trust me again? It's so hard to change knowing that I made you like this....can't you forgive me already?"

Jungkook sigh and wrapped his arms on Jimin's waist, kissing Jimin forehead before going into deep sleep.
"Don't leave me again please..."

It was night time but Jungkook had plans for the both of them.
"Get dress"

"What why?" Jimin asked, confused.

Jungkook smile softly.

"Let's go have some fun hyung"

So they did, Jimin was having a splendid time. He was really happy. Jungkook was happy too.

"HAHAHA your face is so funny jungkook!"

"Hey! I'm still handsome okay?"

Jimin roll his eyes. "Whatever jungkook"

"Hyung~ call me kookie or jungkookie"

"Why should I?"

Jungkook pout. "Please~?"

Jimin sigh and smile cutely. "Okay kookie~"

Jungkook smile widely and kiss Jimin on the lips. Jimin gasp in shock. He wanted to push him away but jungkook was fast enough to put both Jimin's hand onto his.

They kiss for a good minute before pulling away.

"Hyung?"

"Y-Yeah?"

"I love you...will you be my husband again?"

Jimin thought for awhile.
Is he lying to me again? Is he worth it? Do I really love him?

Jimin just chuckle, shaking the thought. Oh well...

"Yes Kookie I will"

That was enough for Jungkook to say
"YES!!"

Note:
Done. Hope you enjoy :)

Bye bye~
