______________

Sewon was madly in love with Namjoon and Namjoon was way into Sewon after he laid his eyes on her. Jimin was friends with them through Sewon but wasn't a fuckboy like Kai and Namjoon.

Kai and Namjoon shared everything with eachother. They were the Damon and Pythias of the territory. Kai had problems he rushed to Namjoon, Namjoon had problems he rushed to Kai.

Kai was happy when Namjoon and Sewon officially announced that they had started dating. But Jimin?

He was heart broken. He never told anyone but he was consuming himself after he saw Sewon talk about Namjoob 24/7 to him.. He thought he and Sewon had chemistry but....he loved her secretly and always wanted the best for her. And so, when he saw she was happy with Namjoon he slowly started to close his feelings for her but it wasn't possible.

And so his friends brought a way, drinking.

On his one shot, he felt as if every scar in his body has been erased and that's how he became addicted and used to stuff like this.

Namjoon was a fuckboy and Jimin never wanted Namjoon to only 'fuck' Sewon cuz she was precious. He wanted him to love her which made Jimin vulnerable about Sewon. But Sewon was sure of the fact that Namjoon truly loves her when he started changing himself for her.

Namjoon completely got out of his drinking habit, whenever Kai would call him out he'll ditch him to maintain his sacred side for Sewon. He wanted her to feel happy and loved.

Namjoon finally got a job in Seoul and he had to move there for the better.

"I'll miss you so much!"

"Babe, I'll miss you more and that's a fact. I'll write you letters every day and I'll keep in touch,"

"Don't go!" She teared up.

"I don't want to. But in order for you to have the life you deserve I have to and I promise I will work so hard there that I'll call you one day and surprise you with my own house. So that my sister can have a sister too,"

"I'll pray for you. Promise me you'll never change? Promise me you won't leave me?"

"I promise," he kissed her forehead.

"Namjoon just remember one thing...." she paused to look into his eyes. "I can't live without you,"

"Likewise my love. Likewise," and they attached lips.

Sewon was sure of the fact that even if Namjoon had fucked her twice he wasn't going to use her. He radiated love, he radiated energy and he radiated the vibe that his soul would expire if Sewon even was sad because of him.

"Good bye...." and who knew that would be the last good bye when,

SEWON COMMITTED SUICIDE.

-Jimin was numb and devastated.
-Kai was paralysed and not in his senses.
-Tae and Yoongi tried to keep their shit together in order to handle Jimin and Kai.

"H-how....how so suddenly?" Taehyung inquired before Yoongi pulled the letter out of Kai's hand.

Dated: 12th June,2016.
"Sewon? I hope you're doing well. Look Sewon I'm really settled here in Seoul now. I need to focus on my work, my apartment my sister my needs. Things don't always remain the same. My feelings for you have died or maybe they never really were there for you. I just fucked you, used your body for myself and yeah I loved you but I never felt loved by you. It was just lust but sooner or later you must realise this fact too that now I'm not the Namjoon you loved. I'm a fuckboy and my first priority is fucking. That's it. I'm never coming back to Busan and if you're waiting for me with hopes then you honestly shouldn't. And stop sending me these stupid letters. I have to throw them away and bin gets full. Bye. Never contact me again bitch
Plus, you have nice booty,"

The grip of Jimin's punch got tighter as his eyes got redder and rage rose when he listened that Namjoon used her.

"She's no more," Kai laughed and Jimin sat infront of his wheelchair.

"Kai,"

"No Jimin. My sister is gone. She's....wait she must be dancing in her room like you taught her right? I must go check up on her," Kai was insane at the moment and Jimin couldn't watch anything so he left the house to cool himself down until Tae caught up with him.

From that day onwards, Jimin became Namjoon, a mere worthless fuckboy, a person without feelings, the pain and agony inside him of not treating Sewon with his love and most important the grief of not ever telling her that he loves her, lead him to fuck which put him to slumber and peace.

And so he with each passing day became the Jimin you guys read in the story behind.

As for Namjoon,
Dated: 12th June, 2016.
"Namjoon, it's Sewon. I'm losing faith in you. In us. I don't want to keep my hopes up with your shitty business anymore. I want to be free and not into this long distance relationshit. This is shit and I've moved on from you too. It's better that you never contact me and never send me a letter again. Please delete me out of your life cuz I'm done with a fuckboy like you, asshole. Bye,"

Namjoon still made many calls only to be answered by no one cuz Sewon was no more. He still wrote letters, waiting for months to recieve a reply but there wasn't a reply until it was 4th December, 2016.

"Found your letters but threw them away like I've thrown you out of my life. Please let me be at peace you sucker,"

He was hurt yet happy that he atleast got a reply from Sewon via email. He wrote another letter but after that letter there never came a reply until one day through Jk he discovered Jimin's email. He sent emails to Jimin but he never responded. He tried to make contact with Kai too but they all just disappeared. He wanted to go to Busan but everything was so costly at the moment that he couldn't and his sister also needed him at that time.

He came across Susane, Sewon's friend in Seoul when she was leaving the bank. He instantly stopped her and begged her to tell him about Sewon but the reply only killed Namjoon when he got to know that Sewon committed suicide at 15th June.

It was all very unbelievable for him and for weeks he used to think about everything. How so suddenly. Then he came across the email marked as 4th Dec. If Sewon died at 15 June then how come she was able to send the email at 4th Dec. He still had hope that maybe she is alive.

____

"He has a sister right?" Jimin's eyes were piercing Hana's smile on the frame.

"Yep. That's his sister. Hana."

"Now it's time I'll be Namjoon and she'll be Sewon." He crumpled the picture and threw it at Kai's feet who begged Jimin to get the revenge. If he cant bring Sewon back, he can torture her killer by attacking his sister.

"I will get that revenge for you Kai." Kai couldn't as he was paralyzed.

Just wait and watch how I play the game so smoothly. Just wait and fucking watch.

_______

But the one thing no body in the story knew was that,

the letter that Sewon sent to Namjoon before 12th June had a different hand writing which officially belonged to Sewon.

And the letter Namjoon recieved at 12th June had a different writing which not necessarily belonged to Sewon.

Same,

The letter Sewon recieved at 12th June had a different writing than the letters Namjoon used to send before 12th June.

The only thought of the other breaking up with one engulfed them and it was all momentary that both of the parties didn't focus about the writing but they focused more at the thought of leaving eachother so they made hasty decisions.

Which means, neither of them wrote the letters to eachother. There was a third party involved into this who exchanged the letters and who was responsible for all of this.

This is the main plot.
