That night, thoughts swirled through Jungkook's mind and kept him awake. There were so many things he wanted to say to Jin right now that he couldn't do so he turned on his bedroom light again, put a stack of papers on his desk and wrote a letter:

     Hyung,

     This letter is for me before it is for you and before you say that I am selfish, you have to know that you may never read it. Tonight, at a time when spirits are supposed to be appeased in the rest of sleep, mine is tormented. I know you don't like too cheesy talk and statements and you know I don't like them either, but tonight I'm not in the mood for jokes so I won't coat my words behind a barrier of laughter. You are going through difficult times, and I know that you will hide behind your smile and your humor from tomorrow so I will be the one of us who will not ignore your suffering and who will face it for you.

     During our beginnings, you were the shoulder behind which the shy and scared boy I was hid and felt safe. This shoulder was also the one I rested on when everything got too intense for me, the one I buried my tearful face on when emotions washed over me. Growing up, I tried to forge a mind as strong as yours because you were my role model, but most of all I managed to sculpt a body more powerful than yours. I know what you're gonna say: I said I wasn't gonna make jokes. I'm not convinced that is one, more of a funny truth. 

      Anyway, I wanted to become a strong person myself, a strong shoulder for you and if, on top of that, I could give you back even a little of everything you had given to me, I would have been happy. I don't know if I succeeded, you would have to tell me and for that I would have to find the courage to ask you directly. Am I afraid I haven't done enough? Or am I afraid of appearing too cheesy? How hard it is to overcome my pride... But you know me.

     Without necessarily having succeeded in becoming a support for you like you were for me in my younger years, I think I managed to become a precious friend. This is what you have become for me too. No, it's more than that ... our bond is strong enough to say that we are soulmates. Many people think so, but they cannot be as convinced as I am. Spending time with you made me become a person I never knew I would ever become. Your personality, such a luminous candor, is a gift, it could make me smile endlessly but it ended up making me feel like I'm older than you and must protect you, isn't it strange as a turnaround? 

      Our bond today is stronger than it was before, and you have become a vital person in my life. You unconsciously filled in all that was lacking in my existence and I, unconscious, never thought about preserving this precious bond because I didn't think it could be broken.

     Therefore, during the press conference, when you announced that you were ready to leave the group to fulfill your duty to our country, I was shaken because I saw our bond on the verge of unraveling and I must to re-tie it firmly. You say you're ready to go but did you think about asking me if I was ready to let you go? 

     I am answering you now: I am not. Without you, my universe would collapse: you are everything to me, that means without you I am nothing... Did you ask my opinion when you said you were ready to go? I would have told you that you were wrong, that you still had the right to be a child for a while longer with me, for your happiness and for mine. Don't do what makes you and me unhappy, please.

     When I saw the company tirelessly attack you, I understood that they were trying to separate you from us and I decided, after today's incident, to declare war on them for you, to protect you. They won't make you leave; I will stop them. If they don't like you, they can just go on their own. You are my everything, but you are also for the millions of fans who love and support you. I will fight for them too. So think about them too before you say things like "I'm ready to go." They are not ready to let you go.

     My battle plan is secret, write on other pages. If you read them, you would certainly laugh, but I will keep them away from your eyes because I would feel ridiculous if you understood the meaning of what is written in them. Did you write your own secret battle plan like me to defeat your enemies? Could our souls be connected to this point? I wonder...

     I want to keep having fun and laughing with you. No one knows how to relax a stifling atmosphere so well as you: how could I breathe without you? This is the Jin hyung I want, not the one who is depressed and is convinced that he is incapable. I will fight for you hyung but I would love to do it by your side. Yoongi hyung says you are the most immature of us but he also says you have the strongest mind and I agree with him, so please, don't give up and stay by my sides.

     Now that I have got these thoughts out of my head, maybe I can finally fall asleep with my mind free? I hope so. Until tomorrow, I hope you can heal your mind and fall asleep in peace on your own.

     Stay strong.

     JK.

     Jungkook felt his eyes sting with tiredness. He folded and put his letter in an envelope, put it in a drawer, then went back to bed. Freed from thoughts previously locked in his mind, he fell asleep almost immediately.

     On the envelope, he had taken care to specify the identity of the recipient of the letter:

     My universe.
