"Sulli-ah! Hurry! The bell will ring soon!" a cold looking girl said. The cold looking girl was standing beside a girl as beautiful as the summer's dream, with her oh so gorgeous silky hair, filling the room with a peach like fragrance, bending her knees in the floor behind a student who fell asleep studying for the short quiz that his professor will give later.

"Ssshhh! Shut it! He'll wake up" the innocent-looking girl whispered, scared that her beloved friend would wake the prey up. She slowly pinched the glue that she brought in the middle of the chair and the student's bag. Thinking of her ingenious scheme, the innocent-looking girl laughed and said "Oh boy! I can't wait to see the look of his face". She stood up, half-smiling, trying so hard to hold her laughter.

The cold girl flipped her hair, giving off an aromatic fragrance. Her body is definitely something to die for. If you were witnessing this, you'll definitely say that she's the chicest girl that you'll ever met. No wonder why boys are over her, and even girls are turning into something that they shouldn't be. She gave her dear friend a smirk.

"Now, let's do our part. Should we?" the cold-looking girl said, brushing her friend's hair.

The other girl let out a warm smile and said, "With honor, milady!" She held her friend's hand and, together, they went to a hidden spot in the library, their favourite spot, the place where they could freely hide from anyone's attention, which became a big burden for them. The innocent girl chuckled.

The bell rang, but, unexpectedly, the student remained in his dreamland. "Pfffft!" the cold looking girl said, trying her best from bursting into laughter. They were peeking and the fact that the student didn’t wake up makes the game more interesting for them. The librarian noticed the sleeping student so she walked towards him and slapped the student's head. Well, the librarian was well known for her slaps anyway.

"Ouch!" the student shouted. The librarian leaned and gave him a death stare.

"The bell rang! Go to your classroom, stupid kid!" the grumpy librarian said.

"Look at him having goosebumps!" the innocent looking girl whispered to her dearest friend. The other girl let out a silent laugh.

"Y-yes Ma'am!" the student said and stood up. He held his bag and put force to carry it but his bag was glued in the chair.

"What the-- what is this!?" the student said while he leaned to check the white substance holding his bag.

The librarian knew exactly who did the trick."Sulli! Krystal!" she shouted, which made the girls giggle. The librarian's angry voice is like a music to the girls' ears.

"Hul! It's louder than yesterday. Our librarian is daebak! Ah! She broke the record!" the cold looking girl said, making her friend laugh.

"Ya, she called for us. You heard the lady, we give her what she wants, right? Ready?" the innocent looking girl said. The cold looking girl smirked as she nods her beautiful head. They stood up and slowly, they showed themselves to the grumpy lady.

"Hi, Ms. Park! You called for us?" the innocent looking girl said, putting a puppy face, hiding the demon inside her. The cold-looking girl walked beside the grumpy lady and seductively brushed her hair.

"Unnie~~~ You're looking more beautiful each day" the cold looking girl said. She then leaned closer to the grumpy lady's ear. "Totally my style~" she seductively whispered. This gave chills to the lady. Somehow, the lady wanted more but she need to resist or else, she'll fall right into her trap.

"Omo! Onew-oppa! What happened to your bag!?" the innocent-looking girl said as she hurriedly walked to get a closer look of the bag. The man knew that he just became a prey but he couldn’t do anything about it. As long as it's these girls, NO ONE would ever dare to do something against them. The man couldn’t do anything but to frown. He hopelessly looked at the librarian, his only hope, but this day is definitely not his day when he saw the poor librarian being hypnotized at the cold girl's effortless seductive gaze.

"The bell rang already, right?" the innocent-looking girl said, pretending to look at her watch. She turned around and looked at her dearest friend. "Soo Jung-ah, let's get going! It's already time. Onew-oppa, we'll be watching you~" she sweetly said but it sounds like a death threat to the man's ears. The man couldn’t say anything and let out a cold sweat.

The cold-looking girl smirked and, once again, leaned to the lady's ear and said, "Unnie, see you later~". She then gave a wink to the hopeless lady. The innocent looking girl held her friend's hand and, together, took their escape, leaving the two victims speechless.

As they were walking out, they bursted into laughter but they didn’t made it obvious. "The look at her face is daebak! We used your skill very well, Soo Jung-ah!" the innocent-looking girl said, which made the cold-looking girl giggle.

A charismatic short-haired girl, who somehow looks like a handsome boy, welcomed the girls the moment they stepped out of the library.

"I see what you did there" the short-haired girl said. The innocent girl let out a smile while the cold-looking girl couldn’t help hugging that person

"Stupid! Where have you been? You should have called us! Omma and Unnie are also worried!" the cold-looking girl said, with a worried tone in her voice, with the innocent girl nodding. That person suddenly disappeared without telling anyone for three days, and believe it or not, this person is friends with that demonic girls. The charismatic girl raised both of her shoulders, shrugging.

"I went to Los Angeles to pick up a friend of mine because he wanted to study here. Now I lost him" she said, causing the two girls nod in amusement.

"But stupid! Did you eat already?" the cold-looking girl asked. The girl shook her head. The innocent-looking girl wrapped her hands in that person shoulders and said "Hyung, you should eat first then we'll help you find him".

"But you're supposed to go to class" that person said, which made the two pranksters laugh so hard. The thing is, these two barely even go to class but can still make it into the top, especially the innocent-looking girl; of course, by pulling some strings.

"Pffft! You just came, is class important right now? Soo Jung and I just have to pull up some strings again and just do what we always do so why are you even worried? Geez!" the innocent-looking girl said, doing some aegyo for the friend that she missed a lot

"You know what? You two are dummies!" that person said, a sign of giving in. After talking about that person's travel to Los Angeles, they began walking to the cafeteria.
