3rd person Narration

The week has been flown very fast, Rain and Sehun relationship is still strong as a rock or a steel. The Queenka and Kingka contest too is fast approaching. Luhan and Rain already have practiced and memorized all their parts. They also conditioned their bodies for the fashion show/s. 

It's just a normal day for Rain, she sat on her chair and waited for their adviser to come in. Unexpectedly her Adviser is not alone. He's with someone. Not just someone but someone who 'almost' look like Rain. Rain's eyes almost pop out of her face on what is she seeing. All of her classmate gasped and look at Rain and back to the girl. 

"Class, Meet your new classmate" The adviser said

"Annyeonghaseyo~" she bowed and smiled

"I'm Sunny Lee! Please take care of me!!" She beamed and bowed again. God!! Is she my loooong lost sister?! ! I look like her!! Rain mentally shouted. 

[A/N: Sunny is not the Sunny who's a member of Girls' Generation ^^ I just made up that name.] 

Sunny scan the whole room and her eyes bug Rain. She smiled at Rain who is jaw dropping. She look back at her teacher and smirked. Be ready, Rain. Sunny thought. 

"Sit there" The adviser said and pointed the chair next to Chanyeol. 

"Neh~" Sunny said and walk through the class. But before she can go to her place she stop in front of Rain . 

"Hi, sister!" she said and smiled, Rain just look at Sunny with confused eyes. 

"We should talk later" Sunny whispered and Rain just nodded cause she can't find the right words. 

Rain just sat on her place with floating questions on her head. Is she my half sister too?! Sh*t my Dad is such a playboy!!!! Rain mentally shouted. She ruffled her own hair and knock her head on the desk. She felt a tap on her shoulder and look at him. 

"Are you okay?" Sehun mouthed, Rain shook her head and pouted

Definitely she's my sister cause I look like her and her surname is Lee too. Rain thought. 

She just slept at the whole class until the bell rang and woke her up. 

"Rain you just slept" Sehun face-palmed

"But Oppa, I have problem" Rain pouted and glanced to Sunny who is busy talking with Chanyeol. 

"Really? So she's your sister?" Chanyeol asked

"Yeah, but she doesn't know" Sunny said

"That's why you two look alike!" Chanyeol beamed

"Why are you so happy? tsh" Sunny smiled and slap chanyeol slightly

Actually I'm happy cause, If I can't have Rain, I can have Sunny!! Wohooo! Chanyeol cheered. 

"Rain!" Sunny stood up and walked to Sehun and Rain

"Hi!" Sunny greeted Sehun

"Hi" Sehun said with a straight face

"So you're my sister??" Rain asked

"Yeah" Sunny said and pouted. 

God!! Even my gestures! She got my gestures!! Noooo!! Not the cute parts ;_; Rain cried inside

"How? Are you my step-sister? Who's your mother?" Rain asked

"I'll tell everything to you, privately" Sunny said while looking at Sehun

"Sehun is fine with me~ Besides, he's like a family to us. Cause he's my boyfriend" Rain said and hold onto Sehuns' arms

"Woah, Boyfriend! Wow, so handsome" Sunny said and hold Sehun face. Sehun flinched and slap Sunnys' hands.

"But his attitude is not good. But still! Kyaaaah!!" Sunny squealed

Oh! No!!!! Sehun mentally shouted and wanted to run. Rain glared her sister and Sunny noticed that so she zip . 

"Let's talk this things out, Ka
