The mountain roads that are usually quiet will always be noisy with screaming sounds and the sound of motor engines whenever there are the hordes of teenagers doing a motorcycle racing there. Just like today, the mountain road was filled with commotion.

"yak!! Joon Woo-ah! Hyun Ki-ah!! Fighting!!" yelled Hyang amid the screaming voices of other supporters. Meanwhile, Dae Jun and Myung Sik also give their support to their two friends who will compete with their expressions and eyes.

Hyun Ki leads the race with Oh Nam Gil in second place and Joon Woo in third place. There was only a very small distance between the three of them. They continue to pull their gas at the maximum speed. After passing a few laps until they reached the last round, Hyang, Dae Jun and Myung Sik continued to shout their friend's name. Nam Gil tries his best to reach Hyun Ki and is so desperate to win the race, so is Joon Woo.

In the final corner, Nam gil managed to reach the handsome teenager motorcycle that was in the first position. The intruder tries to cheat by continuing to push Hyun Ki's bike around the corner. Nam Gil's actions are really dangerous and can knock the student off the main road and fall. Hyun Ki keeps his balance so he won't fall even though Nam Gil keeps pushing him out. If Jae Hyun wasn't careful enough, he might have fallen into the abyss.

"yak! He's cheating! Yak! Oh Nam Gil!!" yelled Hyang enraged after saw her friend who was pushed to the corner of the street. Myung Sik and Dae Jun also feel angry like her, they are eager to teach Nam Gil who is trying to harm their friend.

On the other hand, Joon Woo who sees how dirty Nam Gil's game is pulling the gas even harder and tries to reach them. When he saw the gap between Nam Gil and Hyun Ki, the tall and narrow sharp-eyed boy quickly rode his motorcycle and made himself come between them. He then made a small move to push Nam Gil and put his opponent off balance. The cheating student changed the direction of his motorcycle to the right when he received Joon Woo's surprise attack. Because of this, he almost hit the side of the road.

Finding the opportunity, the two angel-devil members immediately accelerated the pace of their motorcycles and left Nam Gil far behind. The two smiled at each other then quickly reached the finish line together. Hyang and the other two gang members cheerfully welcomed their friend who became the winner. The race was a match between two gangs, The Angel-devil from the SEC's elite school and the Blackhawk gang from the other school. The members of the Blackhawk gang looked at Hyang and his friends with expressions full of anger.

Hyang and the rest of the members approached Joon Woo and Hyun Ki with a big smile on their lips, they patted their friends ' shoulders with a lot of pride. The spectators who watched the race also approached the five members of the Angel-devil gang, some girls seemed excited to take pictures together with Hyun Ki and Joon Woo. When Hyang saw Nam Gil who was not far from her, she then walked quickly towards the student.

"give us the money bet," Hyang told Nam Gil.

The student glared at her with a piercing gaze but still handed her the money. After the girl receives her money, she then hits Nam Gil in the face as payment for what he did to her friend. Nam gil felt angry about it, he then pushed Hyang hardly and in a short time his gang members had already surrounded Hyang. Joon Woo and the others immediately approach Hyang and confront the opposing gang. Nam gil was shocked when he recalled how his gang had been defeated by Angel-devil in their fight last time, he then stopped his members from starting the fight.

"I'll make sure you'll pay for it later" said Nam Gil walking past the slender girl and pushing her with his body.

Hyang only rolled her eyes because she felt upset but she also tried to restrain her anger not to fight anymore. At least Nam Gil has received punishment for putting her friend in danger. After Nam Gil's gang leaves, the girls around "Angel-devil" approach the boys again and are busy taking pictures of the handsome men who are members of the gang, of course without Hyang as she is the only girl.

Actually, the other members were not very interested in the photo shoot except for Myung Sik who was busy posing and pretending to be a handsome man with a standard face that was much different from the three handsome friends .

"Dae Jun oppa, can I take a picture with you?"asked one of the girls with a cheerful smile. It seems like all the male members of Angel-Devil have their own fans but again except Myung Sik.

"don't smile in front of me because you make me want to kiss you, don't cry in front of me because I want to hug you" said Dae Jun smiling before leaving the girl without giving her his picture.

Myung Sik only looked at Dae Jun with an annoyed look while Hyang and the others laughed at the expression of the super tall student. Actually, he is just jealous because all his male friends have fans from among the beautiful girls especially when Dae Jun tries to show his charm in front of the girls.

"ommo... he's so cool..." the girls' words melted from seeing Dae Jun's smile.

"he smiled at me! Wow... he smiled at me!"shouted one other girl excitedly.

"unfortunately, we failed to take pictures with him..." she added .

Myung Sik who overheard their conversation approached the girl with a "cool" smile on his face. He showed his best proses and getting ready to be photographed but none of the girls cared about him and left the boy just like that. He cursed them for it and made his other friends laugh even more at him.

Angel-Devil then went to the nightclub they used to go to every day, well, at their age and their status as high school students of course they were not actually allowed to visit any nightclub. Joon Woo has taken advantage of his background as a yakuza family to threaten the club guards and Hyang uses their money from the race proceeds as their pocket money.

They then had fun in clubs, danced and even drank booze, something that was not common for high school students. After the music stopped, Dae Jun went on stage and sing several songs. He received a standing ovation and a cheering voice from his friend and the rest of the audience. He then sing a beautiful song to everyone.

On the other hand, Myung Sik is still trying to tease the girls in that club and trying to be cool. When there was a girl laughing and passing by, the tall student would stop her and smile at her.

"don't smile in front of me because I want to kiss you, don't cry in front of me because I want to hug you" Myung Sik said by copying what Dae Jun said earlier in the hope that the girl would melt because of his words.

"what's wrong with him?" asking the girl to her friend and just passing the student made Myung Sik gawk because of the mistreatment he got.

"Plakk!!" suddenly Myung Sik received a hard blow on his head. He covered his head and turned around then found Hyang standing in front of him.

"Yak appo!" Myung Sik shouted in pain.

"stop that" Hyang said in a cold tone, she just couldn't stand it when the giant student tried to act pretentious when it didn't suit him at all. Myung Sik immediately lowered his head because he was afraid of Hyang's rude behavior, well, it wasn't something new when the girl's bad temper re-emerged. She could easily feel angry with anything around her, cursing, and even yelling at everyone, but she never really meant that to her male friends.

After Hyang leaves Myung Sik, the student then immediately approaches Joon Woo and Hyun Ki while Dae Jun has just finished his performance.

"she hit me again..." Myung Sik told his friend about Hyang's behavior to him.

"it's your own fault for constantly flirting with girls, your attitude is annoying you know?" Dae Jun said in response.

"I'm just trying to be like you guys, why are you all surrounded by the girls but I'm not?"Myung Sik said in sulking.

Joon Woo called his friend a fool and laughed at him, did he really not know the reason? In one glance everyone also knows, all the boys in their group have good looks and charming face..... except Myung Sik with his mediocre face.

"but still, she hit me so hard" Myung Sik added while stroking his head.

"Well, she's not our bad girl for no reason" Joon Woo said and smiling. Hyun Ki immediately confirmed his friend's words.

"yak guys! Let's go home, I want to sleep " said Hyang who suddenly appeared with a sleepy face, she was a sleeping beauty and it was already midnight, so it was not strange that the girl was already feeling sleepy.

"alright, kajaa!" said Joon Woo wrapped his arm around Hyang's shoulder and took the girl out of the club while the others followed them from behind.

When the five friends had reached the outside, they were greeted by hordes of male students who gathered in front of the club and brought some wood and other batting tools. In one glances it can be seen that their number revolves around twenty boys with Nam Gil as the leader. It seemed like he wanted to take revenge on the small gang about what had happened when his gang was defeated by them . He also wanted to make up for the embarrassment he received from their previous races.

"akh what is this?" curse Hyang feeling upset. Joon Woo removed his hand from Hyang's shoulder and immediately stood up straightly, preparing to fight.

"well Oh Nam Gil, why can't you stop bothering us? Looks like you really want me to break your leg, huh?"ask Hyang in a cold tone.

"let's see who will enter the hospital among us" replied Nam Gil with a tone as cold as Hyang.

"how annoying... it looks like we have to beat every five people in a row, let's make it faster" Hyang said to her male friends. The four of them replied with a smile in their eyes.

On the other hand, Shin, a former fighter with tall and muscular stature, is in the middle of an investigation into a new case related to ACO. He was now in front of the building where the person he was following was inside. There was a man suspected by Shin, that man was also a fighter.

Shin had seen him when he was still a fighter. He remembered that the man he was following now used to be always close to Se Hyuk in the past before his enemy died, he also remembered seeing Se Hyuk and the man having a secret conversation, that's why Shin thought that it was possible that somehow the man would lead him to know more about the secret organization ACO.

After waiting for so long, the man finally appeared from inside the building. Shin stepped back trying to hide himself behind a wall. The man did not notice the whereabouts of the detective, he leisurely walked through the street. Shin continued to monitor his movements but kept a safe distance to make the man unaware of his whereabouts.

The man entered a small and empty alley as did Shin. The detective did not know where the man was going and continued to follow him. After following him for about ten minutes, suddenly the man stopped at the middle ground, he began to sense that someone was observing and following him. He then continued his steps and pretending not to know.

The fighter led Shin into a more crowded street, and then he took a left-turn road at the intersection. After turning left, he could see a crowd of teenagers fighting in front of a nightclub. He grinned to himself, feeling like he had a chance to distract the one who followed him. Before Shin could approach him, the man suddenly ran into the middle of the fight. The detective was surprised when he saw that the man suddenly escaped from his sight. He tried to follow him again but he felt confused when he saw the crowd caused by the teenagers who were fighting. He tries to find the man among them but he fails to capture his shadow. In that place it was too dark and crowded with brawls, let alone men who were followed before wearing dark-colored suits as well. He tried to focus on finding the person he was looking for among the teenagers but his eyes caught another figure of a girl who seemed familiar for him.

He had no desire to stop the fight between the teenagers before because he didn't care about them, even though he was part of the police force, but he was a detective. He had no business of disciplining those naughty teens. But after he saw the figure of the girl he knew in the middle of the brawl, his little eyes immediately widened in surprise.

"what?" he asked himself who felt absurd with what he saw, how could a girl fight like that, let alone she was the only girl there. The girl had just snatched a piece of wood from one of the boys violently and pounded the wood in the stomach of her enemy hardly.

"she's crazy!"curse Shin when he sees again a girl who had made him soaked a few days ago.

"dooorr!!"The detective launched a warning shot into the air, making the teenage gang brawl stop and immediately searched for the source of the sound.

"it's the police here! Stop there!" Shin shouted to them. The teenagers were shocked and stopped their fighting, they began to flee in all directions.

"Hyang-ah, let's go!"yelled Joon Woo who was standing not far away from his female friend .

"guys, come on!" she yell at the other members. They start to run away and try their best not to get caught by the police.

When Shin saw Hyang start to running away, he ran quickly to approach her. He didn't even look at the other way and went straight past some teenagers who were also involved in the brawl before, he just focused on Hyang and was eager to catch her, he didn't know why but he really wanted to scold her. Hyang tries to run as fast as she can, but unfortunately Shin is much faster than her. In the blink of an eye, Shin was able to catch her, he immediately grabbed Hyang's hand and turned the girl's body.

"aah how is this? Yak! Let go of me police uncle!" said Hyang in panic, with a strong pull she was able to release her hand from Shin. She tried to run again, but this time Shin instead grabbed her waist from behind and pulled the girl closer towards his body.

"aaah! Yak! Let go of me!!"Hyang shouted furiously, she didn't even see Shin's face and continued to struggle trying to escape from his muscular body.

She didn't care who the man who had caught her and just wanted to escape. It really pissed her off when her strength couldn't be compared to that muscular man. And also, she felt very upset by his actions. Among all the people there, why did the policeman just arrest her? Why did he just catch a girl? Is he a lewd cop?

"stop it! Can you?" Shin asked from behind her head while tightening his arms around Hyang's waist. But the girl did not listen and continued to fight. Shin had finally reached the limit of his patience, he then lifted Hyang's body off the ground and upheld the small body with one muscular hand.

"aaah! Yak! Yak! What are you doing jinja?!" she yelled in frustration. She then lowered her head until it reached Shin's hand and bit his hand hardly.

"ouch!"shouts Shin in pain and let her go unconsciously.

When the detective was still in pain and held his hand, Hyang immediately turned around and kicked his leg as hard as possible. The girl made Shin immediately bend over and hold onto his painful legs.

"serve you right!"Hyang said sticking out her tongue to Shin who was bowling his body right now.

"this girl is so outrageous!!"shouts Shin feeling angry. Hyang was surprised to hear his scream and ran as fast as she could before the man could catch her again.

"Yak, Song Hyang! Hurry up!" call Joon Woo approaching Hyang with his motorcycle, the girl immediately sits on the motorcycle back while Joon Woo plugs the gas quickly.

"yak you guys! Stop there!"Shin shouted to Hyang who had gone further.

Hyang just turned her head and smiled brightly as she waved to Shin using her right hand while her left held Joon Woo's waist.

"annyeong ahjussi!! Have a nice trip home!" Hyang said to Shin who was left behind. She chuckled to herself, although she couldn't see the man's expression in the dark but she knew he must have been upset. She just laughed and put her face on Joon Woo's back.

"Song Hyang?"ask Shin to himself remembering how Joon Woo called the girl before.

"what a messy girl!" Shin cursed to himself. He could see the red marks of the girl's teeth on his hands. He then kissed his hand where there was the bite mark with an annoyed face at the thought of her.
