BTS X READER// Undercover (OT7)

The letter

Y/Ns POV
It's crazy. My big brother is here he may be my step brother (same mum different dads) but that's just minor details that no one really cares about. I know he is going to go and live with his friends,exo, but I'm going to cherish every moment I spend with him. Us two have been together through a LOT, when my father passed away he came to London to help me.
     My father was also and agent and his body was never found. For months I lived in denial thinking he couldn't be dead, how could they know for sure that he is gone? I still haven't accepted it but the sooner I do the better.
Knock knock*
"Come in!" I call and Kai opens the door with an envelope in his hand. I pat the empty space on my bed he sits down and hugs me "I missed you" he mumbles through my hair. "So what can I do for you" I ask
"Well you was meant to have this a while ago, when we was in London. But your boss gave it to me and said for me to give it to you when you have settled down a bit. It's from your dad, I promise I haven't opened it I just kept it safe and I feel like now is the right time for you to have it" as his words trail from his mouth he hands me the white envelope "should I go?" He asks while standing up. I grab his arm because I remember that dad was very fond of Kai I'm sure he would want me and Kai to go through hard times together. "Please stay" I say and he gives me a warm smile

My dear princess Y/N,
If you're reading this then I'm sorry. I promised you that I was going to be there for you forever but I guess that my forever was short lived. I want you to do this one thing for me. Get out of this job NOW. Please follow your dreams I have told my brother about your talents and he said he will be happy to take you under his wing and produce your music. I don't know for certain but I have a hunch that my death will be caused by this job, and whoever has come after me will soon be after you. You will be going to South Korea with your step-brother Kai. He's a lovely young man, please let him read this letter I understand it may be personal to you but he deserves to read it as well he really cares about you. Make sure you both look after each other.Don't go after the people who killed me. I also recently found out that you have been diagnosed with depression. Although I am sad that you didn't feel like you could tell me, I understand. I want you to know even though I'm not with you in person please keep me alive in your heart. I will forever be watching over you and your family. Inside of the envelope there are 19 necklaces. I have one on, I most probably still have it on while I'm dead. Give it to the 18 people who you care about most ( you have to wear one ). Also show them this letter so that they understand. Please don't suffer in silence it's the worst thing to do
Love you loads
Appa
I look at Kai and hand him the letter I sit on the bed crying while examining the necklaces which dad left me. When Kai finished reading the letter he hugged me for a long time "don't worry I'm here for you" he whispers while rubbing my back to comfort me. He moves my hair to the side and picks up on of the necklaces and places it around my neck. "You two are forever connected now" his words bring joy to my heart. I now have an actual object to remind me of my father. I pick up one of the necklaces "turn around" I say while trying to get a grip of myself "huh?" He asks while doing as I ask and I place one of the necklaces around his neck.
"Y/N you don't have to" he says while a tear is escaping his eyes "I want to and I know dad would want me to as well. You have done a lot for me and I will forever be grateful" he hugs me again and we cry in each other's embrace.
When me and Kai get a grip and stop crying I finally break the silence "can you tell the guys I want them all to be in the comfort room in 5 minutes" I say Kai immediately knows what it's for "you sure you wanna do this?" He asks with a concerned look. "Yeah... they all deserve to hear this letter and they all deserve a necklace" Kai looks at me and nods then leaves the room. I go to the bathroom and tidy myself up a bit but I can't rid of my puffy face. They will know that I have been crying
From Kai,
They are all here. Take your time x
I don't know what I would do with out him. He's my rock . I head downstairs and take a deep breathe before I step into the comfort room. All eyes on me.
"OMO Y/N ARE YOU OK!?" They all look panicked and worried I just look at Kai and with out realising it a tear escapes my eyes. "Guys let her take her time..this is important" Kai says and the guys look confused but they settle down. I pull out the letter and I can't stop the stream of tears which follow I then give the letter to Kai "o..ppa...c..can y...you" I struggle speaking but Kai understand and nods. He reads the letter and by the end of it the entire room is in floods of tears.
I stand up when he finishes reading the letter "wait here"I say before leaving . I go to my room to get 7 necklaces which my dad gave me, I go into the comfort room and put the necklace around each guys neck one by one. They are all emotional and in shock . "Y/N are you sure about this?" Yoongi asks while giving me a hug "you guys brought hope, happiness and kindness back into my life. Most importantly you taught me how to love again." I finally manage to say a full sentence. We all come together in a group hug "we all love you Y/N you will never be alone. You need anyone to talk to you know where each and everyone of us is"
