Traitor's friend

There are 5 friends named Lisa, Lala, Verisa, Nita and Shella. Lisa is clever drawing, Lala is good at swimming, Verisa is good at making short stories, same with Anita, and Shella is good at making songs and poetry. They complement each other.

One day, in school ..
"Tomorrow's Sunday in the multipurpose hall will be a short story writing competition. A good story will be contested at a higher level. "Miss Chaterine missed in science lesson.
"I want to follow ah, I like to write!" Said Verisa when dikantin with his best friend. "Yee, me too ... good luck yes!" Said Anita. Then the five companions ate.

Sunday…
"Do you want to make a short story of what title?" Asked Verisa to Anita. "Last present for my best friend" Anita replied casually. "Why, really like my title anyway?" Verisa wondered. "You come with me yes, Ver !!" Anita snapped.

FLASH BACK
At that time, Lisa, Lala, Verisa, Anita and Shella were taking Mathematics lessons. They just carry a notebook and a pencil case. Their bags are placed in class.
"Sir, permit to the toilet" Anita said. "Good" Anita went from Mathematics class. Not Anita to the toilet, but to class. He intends evil. He opened the contents of Verisa's briefcase and opened a short story book for tomorrow's Sunday race. "Okay, the title is the last present for my best friend" and Anita drops out of the classroom and returns to the mathematics tutoring room.

"No kok !!!" Verisa replied loudly. Then, Anita told Verisa everything. "Haha, it's delicious!" "The traitorous basis !!!"

Since that time, Verisa and Anita compete in writing and they are not friendly anymore.
