It's a biology lesson and Kim Namjoo is fighting her urge to sleep when her bestfriend Oh Hayoung pokes her arm. Namjoo is thankful and thinking about devil plan to make a class more exciting.

She turns to her victim, an innocent girl Hayoung.

"Young... Youngie..." Namjoo taps Hayoung over and over again until she received her attention.

"What?"

"I'm confuse to what the book is saying here, can you help me to say what is it?"

Hayoung sighed as she knows that Namjoo isn't up to something good. But she can't bear that adorable eye-smile.

"What body part is it?"

"Here, this one."

Namjoo smirk and opens her book to show Hayoung who leaned closer. 

"I'm not sure what is it Joo" Hayoung says when trying to think what is she looking at.

Until........ It's finally click on her, what is Namjoo trying to show her..... specifically what male body part...

"OMO"

Namjoo is holding her laughter as Hayoung is tumbling back from her chair in shock.

Everyone turns their attention to HaJoo place to see what happened and....

THUD....

That was Hayoung's head banging against something.

"Blood! BLOOD!"

One of their classmate shouts. Namjoo immediately jumps down to check Hayoung. She checks her and now bring her bestie to the clinic in the school.

It was different from what Namjoo thought to be, but it was at least more exciting... Except the passed out Hayoung.

Thanks Samsung for making those electronic devices or Naeun would have to witness ChoMi fluffy and cheesy picklines. Meanwhile Eunji is talking about her loves problem to Naeun. When she finally realizes that nobody is actually listening to her.

"Geez, can you guys stop the PDA and Naeun, did you even listen to me?"

"Why I have to listen to you? It's just that you broke up with another girl or boy again? Just settle down already. Stop going around and making out with stranger."

"It's your life that is boring Son Naeun, let's me settle you up with some cool guy, there's guy Lee Taemin who can be your other half."

"Here goes Jung Eunji who is full of herself again" Said Bomi who has been intensely listening to their conversation.

"You know Eunji..." "Thanks but no thank you."

"Why not?" Eunji starts with her eye-smile

"She doesn't trust your taste, that is why" Chorong finally said something and gigled

"Why are you all so mean to me?" 

"Didn't you say you are going to end this things this year?" Naeun said while typing something on the phone.

"Yeah, but before I complete my list, wait, I'm going to tell you what is on it" And Eunji starts to find her piece of paper.

"Don't need to, just do what you want" All 3 girls said in unison

"YA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" Eunji pretends to sob

"ummm... Naeun sunbaenim?"

Some random girl said while bowing 90 degrees.

"Yes? What?"

The girl looks up after hearing Naeun's voice with a worried look on her face.

"It's something to do with your sister..."

"Youngie?" Naeun jumps up from the seat and asks "What is wrong with her?"

"She is in clinic right now...." 

The chair made a screeching sound against the tile and Naeun hurriedly pushes it to get out of the way.

"You guys go to class ahead! I have to go..." Naeun shouts at her friends before running out from the cafeteria. Even is she runs, it's still looks like slow motion for everyone else at the place. Her wavy hairs flipping in the air and her perfect body just gives herself an attract attention from everyone else.

Naeun is usually a calm girl, but when is to her lil sis, she is willing to do everything.
