Y/N POV (6:00 am)

When I was small, I used to trust people very easily...I still kinda do. But, when I was small, people used to tell me to tell them any one secret from my life...and I used to reveal a funny/kiddish secret to people who asked me. But today, I wanna reveal my secret to you...I had an older sister...Kim Jihee...
She's no more. I loved her so much...she was my best friend...my everything. At one point...she was more important than my brothers. But she left us...she suicided. My parents were at my grandma's house when this happened. That day was the worst day in the history of the Kim family.

Flashback~~
Jin: 12
Jihee: 11
Taehyung: 10
Y/N: 9

Little Y/N: Unnieeeee! Can I go to school with you?
Jin: Munchkin...you are going with me and Tae and that's final!
Little Y/N: But what about unnie? *frown and pout*
Taehyung: Noona wants to go by bus, sis.
Jin: Cutie, get your bag. Let's leave.
Jihee: Bye Y/N, Bye Tae, B-bye o-oppa.
Jin: Stop calling me oppa, you nerd. *eye roll*
Little Y/N: *tugs Tae's uniform* Oppa...what is a nerd?
Taehyung: You don't need to know,  lil' sis. Hyung! We're getting late! Mr. Lee might be here by now.

Why do oppas act so mean to unnie. And everyone in school bullies her! They call her that word...Uhh...nerd! Yeah...nerd. Jihee unnie is actually pretty if you ask me. But everyone calls her ugly and fat.
I shrugged it off and went to Chanwoo. My best friend. Obviously after Jin oppa and Tae oppa left. Chanwoo kissed me on my cheek and I blushed.

Chanwoo: Hey Y/N!
Y/N: Hi oppa.
Chanwoo: Lets go for Maths
Y/N: Ne.

We were about to go when suddenly I heard a voice.

Jihee: Y/N-ie...is he your boyfriend? *wiggles eyebrows*
Y/N: Yah! Unnie! He's just my friend...Oh yeah...pleaseeeeeee don't tell oppas. They will get angry.
Jihee: Don't worry...I won't.
Chanwoo: *mumbles sadly* Friends?...Oh by the way, Y/N...whose that?
Jihee: I'm Jihe-
Ramdom girl: *comes and stands next to us* Oh...you mean piggy?
Y/N: Unnie, whose that?
Jihee: No one Y/N...forget it.
RG: Oh, that's your sister? This is so funny...your little brother and sister and Jin are good looking and here we have a pig. Haha.
Y/N: Yah! Jihee unnie is also pretty!
RG: Awww...defending your nerdy "unnie"...you're so cute Y/N-ah.
Y/N: My unnie is not-
Teacher: Y/N...Chanwoo...go to your class...math will start in 5-6 minutes *warm smile*
Chanwoo: Yes, ma'am.

We both left after that.

Time skip~~

No one POV

You and Taehyung went upstairs to play while Jin was watching TV downstairs and Jihee came and called him.

Jihee: Jin oppa.
Jin: *annoyed tone* What?! And stop calling me oppa.
Jihee: Mianhe. I actually wanted to talk...
Jin: What is it?! Ugh! I can't even watch TV peacefully!
Jihee: Opp- I mean Jin...why do you and Taehyung choose whom Y/N hangs out with? She's literally scared of you. I don't think it's good for he-
Jin: Why do you care what we do with our sister. Well, we're doing this for her sake. We don't want boys all around her when she grows up.
Jihee: Ok...
Jin: Now can you go and mind your own business!
Jihee: Oh actually...I need to say something else to you.
Jin: Ugh! What now?!
Jihee: *tears up* These people from my class always keep bullying me. It's getting hard now. They even bea-
Jin: I don't care! Just get lost! Fat ass nerd! Just go die! No one cared about you anyway!
Jihee: You're right! There's no point of me living! I should just die! I hate all of you!
Jin: We never said we loved you *eye roll*

Few days later~~

Y/N, Taehyung, Jin: Eomma! Appa!
Eomma and Appa: Kids!
Appa: Where's Jihee, kids.
Jin: I don't know...we haven't seen her in a while.
Eomma: That's odd. She would have been the first one to come and hug us.
Y/N: Eomma...should I go look for Unnie.
Appa: Yeah. Did she go out or something?
Taehyung: Aniya...she was home all day.

They started looking for Jihee, while you, Jin and Taehyung were looking at other places. Suddenly, you both heard your mom scream.
We saw dad come running in the guest room, where we currently were.

Appa: Jin...take care of these two.
Jin: Ne Appa.
Taehyung: Appa...what's happening?!
Y/N: *cries* A-a-Appa...I'm s-scared...i-is u-unnie o-okay...?
Appa: She is f-fine, Y/N.

After that dad left and I just kept crying. In my brothers' arms.

Y/N: Oppa...u-u-unnie w-will be f-fine...right? *hiccups and sniffles*

My brothers just hesitantly nodded and reassuringly hugged me.

Time skip~~

Jin: Appa...She slept. Her eyes are really puffy and her nose is red because of crying.
Appa: It's okay, Jin. Just keep Y/N in your lap.
Taehyung: *sobs* Appa...it's been 5 hours...will Jihee Noona be okay?
Appa: I don't know, dear. I don't know.
Jin: Is Eomma okay?
Appa: She's crying badly so I called Mrs.Min and all the moms and kids are at their house.
Mr.Jeon: Hyung!
Appa: Junghyun...why did you get Jungkook with you?!
Mr.Jeon: Like your kids...he also started pleading me...Jihee is like a sister to him too.
Appa: Yeah.
Jungkook: Hyung! Why is Y/N looking so pale?!
Jin: She's been crying a lot kook. She just slept on my lap.
Taehyung: Yeah.
Appa: It's been 5 hours and we don't even know why Jihee was lying unconscious in the bathro-
Nurse: Relatives of Kim Jihee.
Appa: Yes. Jin...take care of Y/N, Taehyung and Jungkook.
Jin: Ne Appa.
Mr. Jeon: Hyung...let's go.
Appa: Ne.

—————————————————————————————————————————

Doctor: Mr.Kim...Me and my fellow doctors tried our best but...
Appa: But what?!
Doctor: I'm sorry...she's no more...
Appa: Jihee...

End Of Flashback~~

My mom had to go through god knows how many damn therapys to overcome unnie's death. Jin oppa kept blaming himself for so many days and I kept crying every night. In 1-2 years...we were over her death...painfully. Unnie actually didn't cut herself or anything. She gulped a full jar of sleeping pills. I got down and heard someone talking.

Jin: *sobs* No Tae...Y/N is clearly right...it's all my fault...I should've protected her and love her like I love Y/N. I was always unfair towards Jihee.
Taehyung: *sniffles* No hyung...trust me...you are the best brother in the world...you took care of me and Y/N when you were just 16.
Jin: But I couldn't save Jih-
Y/N: O-oppa...I'm sorry. I m-made you f-feel like that. I- I'm so sorry. Oppa...Mianhe...
N-naega...naega Jinjja Mianhe

Jin oppa got up followed by Tae oppa and started walking towards me and engulfed me in a hug. He pulled away and looked straight into my eyes.

Jin: Princess, you know...sometimes...in anger, we say something we really don't mean. I'm not angry at you...I'm angry at myself. I'm sorry...I couldn't protect your unnie.
Y/N...I already lost Jihee...I don't wanna lose you too.

We three shared a group hug and went back to sleep as it was 6:30 am and we still had 2-3 hours to sleep.

A/N: Hehe...surprising wasn't it? I was about to reveal Y/N and Jungkook's relationship in the previous chapter itself but I suddenly got this idea and yeah...I wrote it down. But I PROMISE to reveal their relationship to Jin. And Yassssssss!!! I updated early!! Annyeong!
