“So tell us, why are we at school so early in the morning?” Jun Hue asked while yawning.

                “It’s finally the D-day, you stupid.” Bi answered.

                “Oh! The D-day! Is it that day today? I totally forgot about that.” Jun Hue said and just smiled.

They (Jun Hue, Dong Hyuk, BI, Bobby, and Sung Jae) were walking along the school hallway while holding some boxes full of y traps. Sung Jae told his friends to go to school early so that they could set traps for So Hyun and her friends.  As soon as they reach their lounge at school, they started to organize all the needed traps to set.

                “Okay, we will set up the traps to 4 different places. One for each of them and it should be a blast for all of them. So, any suggestion on where should we put these?” Sung Jae asked his friends who were listening to him.

                “What if you assign us to whom will we set the trap to? It will be easier that way.” Bobby suggested.

                “Yah! You’re a genius! Why are you in class 3 again?” Sung Jae praised.

                “Yah, yah! Was that a compliment? It’s because I never try, you guys. I’m too lazy for that.” Bobby countered.

                “Yo! You shouldn’t just take someone else’s title. Dong Hyuk’s in charge for that. Just look at him! He doesn’t even care what we are doing here and just keeps on sleeping. It’s called LAZINESS.” Jun Hue reminded.

As soon as Jun Hue said those, all the four of them automatically looked at their sleeping friend on the couch. Among them, Dong Hyuk’s the lazy one. His favourite phrase was “Saving energy is essential to Human Life.” And so, he really didn’t make an effort in everything he do and didn’t even speak so much. Jun Hue on the other hand, was the one who spends too much energy. He did everything with so much effort and with a little too much of enthusiasm. He was the talkative and the most mischievous in the group. Bi’s the serious and ill temper type. He did everything what Sung Jae told them to. He’s the most trusted member among Sung Jae’s friends and he’s the second-in-command in the group. He’s the one who’s in charge of scolding the other members in Sung Jae’s stead since Sung Jae didn’t really get seriously angry. Bobby’s the most intelligent in the group but he didn’t really show it. He really didn’t care so much about his surroundings but he’s loyal to Sung Jae and did what he was told to. Since he’s the most knowledgeable, he’s in charge of gathering information although he really didn’t make an effort about it. Sung Jae’s the leader. He’s a good leader and a friend to all his friends and they all listen to him. Although sometimes he wouldn’t tell them the real reason for doing what they’re told to, they all still believed that everything Sung Jae was doing has a reason behind it.

                “Okay. This time, you’re in charge with Sung Kyoung, Bi.” Sung Jae stated.

                “Understood.” Bi answered and nodded.

                “Jun Hue, you’re in charge with Suhyun.” Sung Jae continued.

                “Alright! Bring it on! It will be a party for her later. PARTY POOPER, that is!” Jun Hue cheered.

                “Keep it down, you idiot.” Bi scolded and Jun Hue kept quiet and was still cheering but silently.

                “Hayi’s yours Bobby.”Sung Jae said to Bobby and he suddenly blushed.

                “Hayi’s MINE?” Bobby thought to himself. “Wha.. What?! What are talking about Sung Jae-ah? She’s.. She’s not my property.” Bobby stuttered and became flustered, his face turning red.

                “Of course she’s not!” Jun Hue interrupted and Bobby became pissed and glared at him. “Sung Jae means that you’ll be in charge of setting a trap for her. That’s all.” Jun Hue continued and looked away seeing Bobby’s angry face.

                “Oh! So that’s what it means! Hah! I thought of it differently. Sorry.” Bobby gave a relieved sigh.

                “Ha! Why were you so flustered? You see? That’s why you’re in class 3.” Sung Jae teased and laughed out loud.

                “Fine, whatever. So, who’s in charge with my cousin?” Bobby asked, changing the topic.

                “It will take a devil to beat a devil. Let me handle it.” Sung Jae concluded.

At the other side of the school:

So Hyun and her friends were in their own lounge (belongs to the past F4s). They were huddled together on the centre table, discussing about their own trap for Sung Jae and his friends.

                “We’re already in Hell because of our new classmates and classrooms. The least we could do is getting rid of those hoodlums.” Sung Kyoung said.

                “You’re absolutely right Kyoungie. That’s why we’re doing this right now. At the end of this day, they’ll surely taste what it’s like to be in OUR version of hell.” So Hyun agreed.

                “Does Hell have many versions? I thought it had only one?” Hayi asked, confused.

                “Hayi, could you just.. If you have a question, could you just keep it to yourself?” Suhyun pleaded.

                “What about Heaven?” Hayi continued asking but this time more quietly as if she was asking herself.

                “Ignore her.” Suhyun told her two other friends. “So, I brought them with me So Hyun-ah. I brought the things that you told me to bring.” Suhyun continued and winked.

                “Great! Good job Suhyun-ah. As expected from Song Woo Bin’s daughter.” So Hyun praised and Suhyun smiled.

“ Hah! These will surely give them a fright.” Sung Kyoung said confidently.

                “Okay, as discussed.. We will start our plan after classes, during club hours since they don’t have club activities yet. We should put these in the designated places before that time comes.” So Hyun explained.

                “I can’t wait to see their faces! It’s finally payback time!” Suhyun sounded really excited.

                “Guys, what’s going to happen? I’m totally lost here.” Hayi asked her friends who were making evil faces.

“Hahaha!” So Hyun, Suhyun and Sung Kyoung laughed evilly at the same time, silencing her.

                “I’ve got a bad feeling about this.” Hayi thought.

The first period has started and Sung Kyoung was about to enter her classroom but she bumped into someone who was also entering the door. Sung Kyoung struggled to keep her balance but was bumped again by the same person and it made her fall on the floor. When she looked up to see who the bastard was, she saw Bi. Blood started to run up her face as she was about to say something but Bi bent down suddenly.

                “I’m sorry! I didn’t see you.” Bi lied and acted like he was concerned by looking for some injuries.

                “Didn’t see me? Didn’t see my !” Sung Kyoung thought.

She was still on the floor and Bi continued to act like he was searching for injuries. He touched her arms, knees and lastly her heels. Sung Kyoung freaked out by his touch and immediately slapped his hands away.

“What do you think you’re doing, you ert!” Sung Kyoung exclaimed and Bi stood up quickly and glared.

“Maybe he doesn’t want to be called a ert?” Sung Kyoung thought. “Hah! In your face! Serves you right!” She added and suddenly their teacher came and Bi ran to his seat quickly and sat there normally as if nothing happened.

                “Uhm.. Yoon Sung Kyoung-shi? Are you okay?” The teacher asked, noticing that she was still on the floor.

After hearing the teacher, Sung Kyoung stood up immediately but was shocked by what she heard and smelled. Every time she would step her right and left foot, a horrible smell came out and a disgusting sound like a fart could be heard. She froze and so did the other students in the classroom. She tried to step again, and the same sound and smell came out. She was so embarrassed and she could hear some silent giggles coming from her classmates.

                “Teacher, I think Yoon Sung Kyoung needs to be excused. “ Bi interrupted.

                “Yeah! She obviously needs to use the Comfort Room.” Jun Hue announced loudly making everyone laugh.

Sung Kyoung glared at them. She was so embarrassed that she could only stand there, bowing her head. She kept on thinking about what was happening and she suddenly remembered something.

“BI! That son of a.. He did something back there when he bumped into me!” Sung Kyoung thought and she then felt something strange on her shoes, like something has stuck on the heels of her shoes. “That’s it! The heel! When he touche
