Oh Sehun's Sister (EXO FanFic)

Uno

Hyerin's POV

"Wake up, Hyerin, it's your first day of school on your new school" Sehun hyung woke me up.

"Hyung, give me 5 more minutes" I told him with my sleepy voice, I call my brother hyung because I love to tease him by calling him hyung.

"Yah!! How many times do I have to tell you to call me Oppa instead of Hyung" he scolded me. Ugh! Here we are again arguing to call him Oppa instead of Hyung.

"Arraseo! Arrasseo! I'll call you Oppa now, just give me 5 more minutes to sleep" I pleaded to him

"Alright, just 6 minutes. Ok?" he told me

"Ne, oppa" i replied to him my eyes are still close, then I just heard my door closed means he already got out.

Oopps! I forgot to introduce myself. My name is Oh Hyerin, I'm 19 yrs. old. I have 2 older siblings, Oh Hayoung and Oh Sehun, the oldest is Hayoung unnie then Sehun oppa and then me. It's my first day of school at Sehun oppa's school because I was in Canada when i was in Elementary till Secondary High School, on my Third year of High School, I transferred to Sehun oppa's school XoXo High School. I have to get up now before Sehun oppa barges inside my room again, by the way we only live together, our parents is in Canada with my older sister Hayoung. Sehun oppa told me his friends doesn't know he still has a younger sibling so he'll introduce me to his friends later at school.

"Yah!! Hyerin are you up already?" Sehun oppa shouted outside of my room, I can hear him shouting even though I'm inside the bathroom

"Yup, I'm inside the shower now. I'm about to finish and change" I shouted back so he could hear me. Didn't i told you about my new uniform? Oopps! I forgot to tell again, my new uniform is so CUTE. I'm done changing, now I'll just go downstairs. Oopps! I nearly forgot my bag. Ugh! WHY DO I ALWAYS FORGETS?? *pouts*

"Oppa! Opp- -" I was cut off when I saw 2 boys seating in the couch while watching t.v when they heard me calling Sehun oppa, the 2 of them looks confused.

"Who are you?" a guy asked me, he looks like a girl (Luhan)

"I've never seen you here before" another guy with eyeliners added (Baekhyun)

"Anneonghaseyo! Oh Hyerin imnida, Oh Sehun's younger sister" I introduce myself to the two of them.

"JINJA?!" the two of them asked me in unison with wide eyes O_O

"Oh! Hyerin you're already here did you introduce yourself to them already?" Sehun oppa asked me while holding his bubble tea I made for him last night.

"Yup! I already introduce myself to them" i replied to him "look at their reactions. Kyeopta ^_^" I added while giggling.

"I can't believe you still have a younger sister Sehun" the guy with eyeliners said

"I'm Byun Baekhyun by the way, just call me Baekhyun for short. But for you, call me Baekhyunnie" he added while smiling widely

"Arraseo, Hyunnie oppa" i replied

Luhan's POV (before Hyerin met them)

*Knock* *Knock*

"Who is it?" I heard Sehun shouted, I think he's in the kitchen

"It's me, Luhan and Baekhyun" I shouted back

"Oh! Hyung what are the two of you doing here?" he asked us

"We'll ride with you to school" Baekhyun replied to him

"Arraseo! But let's just wait for someone" Sehun said. Huh?! Who's that someone O_o

"Come on, Luhan let's watch t.v in the living room" Baekhyun told

"Arraseo" I replied to him and followed him inside. In the middle of watching a girl ran downstairs while shouting

"Oppa! Opp- -" a beautiful/cute girl said she was cut off when she saw us.

"Who are you?" I asked her

"I've never seen you here before" Baekhyun added

"Anneonghaseyo! Oh Hyerin imnida, Oh Sehun's younger sister" she introduced herself

"JINJA?!" me and Baekhyun said in unison with wide eyes O_O. I can't believe that Sehun still has a younger sister and to tell you she's beautiful and cute, our school's uniform for girls looks cute on her, she's like a cosplayer. Then Sehun came.

"Oh! Hyerin you're already here, did you already introduce yourself to them already?" Sehun asked her

"Yup, I already introduced myself to them" she replied to Sehun, she's so cute when she said "Yup" popping the letter "p".

"Look at their reactions they're so cute" She added which made me blush a little. Hope she didn't saw me blush.

"I can't believe you still have a younger sister" Baekhyun said to Sehun "I'm Byun Baekhyun by the way, just call me Baekhyun. But for you, call me Baekhyunnie" Baekhyun added while smiling widely

"Arraseo, Hyunnie oppa" she replied

"Uhm...I'm Lu-han" i told her. Damn. Why did i stuttered infront of her

"Could i call you Lulu oppa?" she asked me too

"Yahh..Hyerin, I'm the only one who could call him Lulu hyung" Sehun toldd her

"Hmp.. *Pouts*" she pouted. Kyeopta! Kyeopta!

"I think I'll call you Luhannie. Is it ok if i won't put oppa in the end?" she added asking me

"Sure, I won't mind" i replied to her while smiling widely

"Yahh...Sehun oppa are we just gonna stand here? We'll be late at school" she said to Sehun

We quickly ran to Sehun's car.

"Who's gonna drive?" Hyerin asked

"Me" i volunteered myself

"Ok!" she said "I'll be at the passenger sit" she added then entered the car

Then the 3 of us entered the car and drove to school.
