It was the last day of school before the weekend arrived. Y/n woke up quickly as today she wanted to find proof to the "lost sister confusion'. She wore this for today:

She grabbed a apple and ran out of her house, not caring to eat properly again. Y/n arrived at the school and saw Blackpink leaning on her locker. She walked towards them.

"Hey guys ! I'm here" y/n waved and smiled at them

"Ah, sweet cheeks I was so worried yesterday" Jisoo spoke

"Sweet cheeks?" Y/n giggled

"Your so cute so that's why we gave you that nickname" Jennie said

"So, what about the bts thing" Rose asked

"Ah well, you know there little sister disappeared when she was 6, I was kidnapped when I was 6. There's a big confusion, but if it's true...they are my brothers and I'll have a family again" y/n said

"WHAT" Blackpink shouted

"Today I'm gonna find proof, so don't think of anything just yet" y/n said

After a while, txt came to them as well. They chatted a bit before the bell rang for the first class. Everyone left to the classrooms.

Y/n's plan was to avoid bts at all costs till she found proof. Bts though were not attending today which, by hearing from txt, made y/n to sigh of relief.

Meanwhile at BTS's house

"Yes...yes..ah thank you Thomas" Mr Kim ended the call. "Well honey, we were right..she is our princess" he spoke to his wife and burst into a crying mess.

Mrs Kim burst into tears as well while she hugged her husband. "My precious gem, I'm sorry we couldn't find you earlier" she smiled with tears.

Time skip after an hour
It was 10 am and Bts started coming downstairs slowly one by one for breakfast. Their parents were already on the table.

"Good morning children" their dad spoke.

They exchanged their morning wishes and started to eat. Their parents has decided to not yet tell their children till they talked with y/n. But little did they know, bts had already asked for a background check on her and they would soon find out themselves.

After breakfast, bts went to the back of an alley where one of their guards had told them to come to for the results of the background check. Everyone was a nervous wreck, shaking as if they were in a blender.

Roger, the guard, arrived.

"Sir, as per the results......Kim y/n is your long lost sister" he said

Nobody spoke, then Jimin broke the silence by excitement. They looked at the results, which clearly showed the DNA test, her name, her past life, her relationship status and more. Everyone cried out their hearts.

"I knew it, she never died, I knew it" hobi said jumping up and down

"Nobody tell mom and dad, we will talk to y/n first" Namjoon said

"Yeah, you guys will probably scare her off" yoongi spoke

"Guys, I am the happiest person on earth" jimin said still jumping with excitement and then swirling around.

"I'm lost for words right now" Jin said and Tae nodded his head showing he was too.

Jungkook was in his own world, he always thought he was the reason she disappeared. But today, he would get to know the truth if her was really the reason why she was gone. He was beyond happy.

"Sorry to disturb this emotional situation but I have to leave now sirs, may I ?" Roger spoke up. Everyone literally forgot he was here.

"Yes you may" Jin spoke, clearing his throat.

"Guys i forgot to tell you but when I bumped into y/n once, I called her a b*tch.. so I may or may not have ruined our first impressions" jimin said looking down.

Bts glared at him. Namjoon contacted Soobin, the sanest one of all his brothers, to ask if he can bring y/n to them after school at xxx park. Soobin agreed.

Hobi and Jimin had a great idea of making a basket full of y/n's favorite foods (they got to know her fav stuff by the background check) and bring it with them to the park for a picnic. So they all made a picnic basket and left to go to the park.

Time skip to end of school
Y/n was walking with Lisa to the bleachers where the others were. Lisa and y/n had almost all of their classes together and so they became the closest bffs. Jennie and Rose were play fighting while y/n, Jisoo and Lisa laughed and watched.

Txt approached them, and then Soobin spoke, "hey guys, y/n can you come with us. There is something very important or rather someone important who want to meet you"

Y/n agreed. She hugged and said goodbye to Blackpink before leaving with them. Soobin, on the way there, said something that made y/n freeze.

"Y/n, just to mentally prepare you, we are going to see bts. And that is because they kinda did a background check on you and you are their long lost sister."

"Wait what" y/n stopped dead in her tracks.

Txt looked at her with amusement. Kai went and hugged y/n, knowing she would be emotional after finding out something this huge.

Then she spoke up, "I kind of found about it today before this but didn't knew if I should believe it."

"Wait what ? How ? When ? Why ? Where ? Who ?" Beomgyu started throwing in random questions without giving time for her to answer.

"Hey hey beomgyu stop, let her speak you dumbo" taehyun said

"Get ready with popcorn guys! Some tea is gonna be spilled" yeonjun said excitedly.

"So it all started when it was lunch break..." y/n started speaking.

BACK IN TIME AT LUNCH BREAK
"Hey guys I'm not hungry right now. I gotta go and find proof so I'll be back" y/n said to her friends

"Oh cmon you didn't even eat breakfast" Rose whined

"Don't you dare call an Apple some breakfast" Jisoo said in a motherly voice.

"Guys let her. She won't eat nothing till she gets rid of the stress and confusion, go y/n and good luck" Lisa said and Jennie nodded in agreement.

Y/n dashed outside of school sneakily and got in a taxi. She asked the driver to take her to xxx hospital. Y/n had asked taehyun about which hospital Bts usually go to. Once they arrived, she paid the driver and then ran in the hospital.

"Excuse me, can you give me the health files of the Kim family. I'm their guard and they asked me to get it" y/n told to the nurse in front of the desk. The nurse immediately got out the files and handed them over to her.

Y/n searched for the information she needed and then widened her eyes.

"Same blood types, same last name, jungkook's face, their names ! That's why they sounded familiar, my....my brothers!"

She handed back the files and left, not knowing whether to believe it or not.

BACK TO PRESENT
"Ah! So that's why you asked me about the hospital" taehyun spoke.

They all arrived at the park soon and txt told y/n that they will wait by the entrance to not invade their privacy. Little did y/n know, the word privacy doesn't exist for them.

Y/n eyes swayed everywhere, trying to find her brothers.

"Y/n....."
