Next Day
Y/n pov
*Beep Beep* *Beep Beep* *Beep Beep*
Y/n: Got up u stupid alarm.
I woke up with ringing of the alarm and went to washroom and did my morning routine. Then I got ready for school.

After that I went down and when I was going  out I heard a voice.
J-hope: Where are u going?
Y/n: School.
J-hope: What about breakfast?
Y/n: I'm not hungry.
J-hope: How are u going to school?
Y/n: By bus.
Suddenly Jin came and asked me the same question.
Jin: Where are you going?
Y/n: To school.
Jin: This early and without doing breakfast?
Y/n: I'm not hungry and it will take more time for bus to reach school from here.
Jin: U are not going anywhere without breakfast and neither u are going with bus.
Y/n: But~
Jin: No buts. Dad asked me to take care of u and also asked u to listen to me.
Y/n: Ok fine.
Then we went to the dining room.

As soon as I went there.
Jk: Hey lil sis.
Y/n: Neither I'm your sis nor I'm lil.
Taehyung: What is she doing here.
Jimin: Don't tell me she is eating with us when mom and dad are not even here!
Jin: Yes she is and she is also going to school with us. (serious)
Vmin: But~
Jin: No buts.
Y/n: It would have been better if you would have let me go.
Jin: No it wouldn't. Now eat your breakfast.
After we finished our breakfast.
RM: Y/n before we go to school we have some rules to tell u and u need to follow them cause u are a Kim now.
Y/n: What kind of rules?
Yoongi: Family is our first priority so don't take others side against us.
Jimin: No talking back.
RM: No arguing, well discussion is normal.
Taehyung: Come home before 10 PM
J-hope: No cussing.
Jk: No boyfriend till u are 19.
Jin: Listening to everyone who is elder to u.
Y/n: Well they aren't rules they are obvious things.
Jk: Huh?
Y/n: I already follow all of them to a certain extent.
Jin: Really?
Y/n: Yeah. I don't have a boyfriend and I don't want to have one, I want to focus on my career. I listen to elders even if I don't like it. U can trust me here. About arguing I don't argue with anyone except Mom for some reasons.
Jimin: What reasons.
Y/n: U don't need to know about that. About family being first priority I already cleared that in Limo that day and now you guys are my family too even if we don't like it.
Jin: Yeah I remember that.
Y/n: I used to go out until 12 when I was in US but since I came here I always come home early. Annd about cussing, I cuss in extreme conditions that to not at elders.
RM: U are not that much of a brat as we thought. It took maknaes 2 months to get used to these rules.
Y/n: Obviously I'm not.
Yoongi: Come on let's go.
Then we went to garage sat in limo and went to school.
We were near to school when I said.
Y/n: Jin-si please drop me here only.
Jin: Why?
Y/n: Cause I don't want anyone to know that I'm your stepsister.
Taehyung: Thank god we have same thoughts regarding this.
Y/n: Moreover if I go with u I'll get attention which I don't like.
Jin: No
Y/n: Please Jin-ssi I listened to u in the morning and I'll listen to whatever you say but please drop me here.
Jin: Ok fine.
Y/n: Thanks

After two days
It's been two days since days since I have been living with BTS. It's not that bad we ignore each other most of time except Jungkook cause we sit together in school so we talk a lot and we have a lot of things in common. Both of us like to workout so we started working out together at our home gym and we both like to dance, etc.
I was in my room sitting and getting bored as I have already completed my homework and revised what I studied today. I want to go out and eat street food but I can't cause I'm new in Seoul and I don't know much here. So I went to the living room to ask someone to come with me.

In the living room
In the living room I saw maknae line sitting and watching football. I fake coughed go gain their attention and said
Y/n: Ahem.. Actually I want to go out and as I'm new in Seoul I don't know much here. Please one of u come with me.

Vmin completely ignored me but Jungkook said
Jk: I will go with u but what will I get in return?

Flashback
Y/n: Minjun-ah I'm getting bored please let's go out.
Minjun: Oh my lil sis is getting bored. I will go out but what will I get in return?
Flashback end

Jk: Tell me what will I get in return.
Y/n: What do u want?
Jk: Help me in doing my homework.

Flashback
Y/n: What do u want in return?
Minjun: Help me in doing my homework.
Flashback end

Jk: What do u say?
Y/n: Done.
Vmin: Damn we should have agreed to go with u.
Jk and Y/n: U lost the chance.
Jk: Go and get ready. I'll also get ready and come in 10 mins.
Y/n: Ok.

With that I ran to my room and got ready.
Then I went to living room and jk was already there.
Jk:So where do you want to go.
Y/n:I heard a lot about street food in Downtown I want to go there.
Jk:U want to go to eat street food?
Y/n: Yeah. Is something wrong with that?
Jk: Nothing, let's go.
Y/n: Let's go with bus.
Jk: Why?
Y/n: Please ( puppy eyes)
Jk: Fine don't give me those puppy eyes.
Y/n: I didn't knew that u were a softy who would melt with puppy eyes.
Jk: Yeah yeah whatever let's go.

After that we took a bus and went to downtown.
Jk: What do u want to eat?
Y/n: Teokbokki
Jk: Okay let go.
Then we went and bought teokbokki and started eating. After that we ate lot of food and talked about a lot of things like movies and games, of course studies was not one of them. Then
Jk: Y/n let's go to a cafe I want to drink coffee.
Y/n: After eating this much.
Jk: Of course coffee tastes best with full stomach.

Flashback
Minjun- Y/n-ah let's go to drink coffee.
Y/n: U pig, u ate so much and now u want to drink coffee?
Minjun: Of course coffee tastes best with full stomach.
Flashback end

Y/n: ok as u wish.

With that we went to a cafe
We went inside the cafe and sat. Just then a waiter came.
Waiter: Good evening. What will u like to have?
Jk: Macchiato
Y/n: Blueberry bubble tea
After taking our order the waiter left and then Jungkook said.
Jk: Yn-ah I'm elder to u.

Y/n: We of same age Jungkook.
Jk: I'm two months elder to u. Even if I was born 1 min before to u. I would be elder to u.

Y/n: We are of same age minjun.
Minjun: I'm four mins elder to u. Even if I was born 1 min before to u. I would be elder to u.
Flashback end

Y/n: Have u accepted me as your sister?
Jk: Yeah. U?
I didn't gave answer to his question and we went back to home.

*Time skip*
Next Day At school
Y/n pov
It's lunchtime and I'm going to cafeteria alone cause BP is absent. I texted them and asked how come they are absent together. They told me that they are cousins and are on a family trip together.

As I was walking towards the cafeteria I saw students making a circle around someone. I elbowed them and made my way through to the front to see Jk beating a guy mercilessly. I quickly went to stop Jungkook.

Y/n: Jungkook-ah stop it. Stop beating him.
Jk: (angrily) Don't stop me y/n.
Y/n: Please stop it.
Jk: No I won't . And why do u care about him. (He said 2nd line shouting)
Y/n: Please OPPA stop it. I don't care about him I care about you please stop.

As soon as I called him oppa he stopped and turned towards me and said.
Jk: What do u mean u care about me?
Y/n: Look at your hand it's bleeding. How hard did you hit him?
Jk: He deserves it.
Y/n: I know.
Jk: Huh?
Y/n: From how much I know u. I believe that you won't hurt anyone without any reason.
This calmed him down. Then I asked someone to take that guy to hospital and I took Jungkook to infirmary.

School nurse was not there so I myself took the first aid kit and started dressing his hand.
Jk: Earlier u called me Oppa. Did u called that to calm me down or~
Y/n- I didn't called u oppa to calm u down.
Jk: Does that mean?
Y/n: Yeah I accepted as u my brother.

Before I could even say anything else he engulfed me to a hug.
Y/n: Are u that happy?
Jk: (bunny smile) YEAH
Y/n: I can't believe that you are the first one I accepted as my brother. U are so childish.
Jk: I only care about u accepting me as your brother. Don't u want to ask why I hit him?
Y/n: No.
Jk: Why?
Y/n: Cause I trust you.
Then he smiled all proud.
I dressed his hand then we went to our class.
