"Jung saeron, this our your last warning. If you don't get your grade improved and fail the final test, you will got a repetition. And with your bad habbit of coming late, your behavior score wouldn't help" the principal said

"okay" Saeron replied

"Now you may go" 

Saeron steps out from the principal office with a melancholy face. She bent down her head as she walk, all she can see is the floortile and her blue-tosca sneakers. Tears starts to flow from her eyes. 

Seoul High classes divided in 6 different class. The a class for the national competition students, b class for the geniuses, c class for the smart one, d class for the averages, e for the almost average , and f for the born to be stupid, badass, lazy ones class. And obviously, Saeron is in F class, with her rank in the class is on the bottom 3.

Does the student have any chance to change their class? Of course they have. They will placed again based on their rank every semester, and every month for the senior highschool. But unfortunately, Saeron had never experienced any class other than F class.

On her way to her class, her ear catching the sound of the guitar harmony that drag her towards the music without concious. 

A boy is sitting alone while playing his guitar with his crossed leg. That boy turned out to be Park Chanyeol, a member of the popular boys in her school, Exo. He is known for his charming smile and good grades, as expected from b class student.

"Geomjeong geurimja nae ane kkae eona
Neol boneun du nune bul kkochi nuntteo
Geu nyeo gyeoteseo moduda mulleona
Ijen jogeum sshig sana wojinda"

Growl- Exo

*imagine Chanyeol sings Growl with an accoustic version*

"Your voice is good... and It's my favorite song" she mumbled
Chanyeol was shocked to see a girl sitting beside him and almost dropped his guitar "sin-since when are you here??!!" He pointed saeron in horror

"Well, since the first chores?" Saeron answered, however Chanyeol notice her tears

"Hey are you crying? Waeyo?" 

"It's just the principal warn me about my grade... if i fail again then i have to do repetition" she explained in the mood of melancholic drama

"Wipe your tears, i believe you can pass the test! Nothing's impossible if you want to try hard!" He pumped his fist in the air. 
But Saeron's tears just stream down even more.

"yah, big girls don't cry, remember?" He wiped her tears with both of his thumb. Saeron stared blankly at him. Suddenly, her stomach make a roaring sound

Her cheeks burn red "I'm hungry..." she pouted. Chanyeol shook his head in disbelieve. 

He rummage his bag and pulled out a chocopie

"Here, you can have this, so please stop crying, okay? You look ugly when you cry" he said with a calming tone.

Saeron grabbed the chocopie and finished it in one bite before she say "Kamsahamnida..."

"Owh... by the way It's my first time seeing you here. I'm Park Chanyeol. What's your name?" 

"Saeron, Jung Saeron" 

Why is my heart beating so fast?! No Saeron no! You can't fall in love with a B class student! You're from F class remember?! He's smart and you're stupid! The two of you together? Duh That's impossible! Remember that!

But even the strongest tornado can't control a heart right?
