She got to the hallway with many students and found Jina standing close to her locker with her friends. She ran to the girl who was oblivious to what was about to happen and pulled her by her hair towards her making the girl yelp, with the way she pulled her hair.
"What the f***," she yelled almost crying now, Liam got there pulling his sister away from her but that was a wrong decision, it….sh… sister had learned judo when she was a kid, and she would go with Lewis. 
Even though she doesn't talk much to her siblings, she learned most of her ways from her elder brother, he is the only one who would always reach out to her when she begins her bratty ways. He annoyed her more and she would chase him all around without catching him. One day doing all those things she begged for him to make her like him, he hesitated at first because he knew his parents would kill him. He bet with his sister which was a wrong decision because she won and forced him to take her. Since then they will both sneak out of the house to learn it.
Liam yelps in pain when his sister steps on his toes and bent his right hand back, making him tap on the ground so she would release him. She ran back to the girl who hadn't regained herself from what just happened. She pushed her friends out of the way and jumped on the weak girl again. Sitting on her she kept punching her hard, Jina's friends not knowing how to stop her jumped on Mary hitting her and dragging her hair but that didn't stop her from hitting Jina. Not long after Soo Min and Trina ran to the scene, they saw the notification on the school site about the fight happening and rushed down there immediately.
The moment they got there they drag the two girls on Mary giving and started having their round of fights with them, giving Liam a tough time to separate the girls not long Woo Bin and Chris also ran to the scene and try to separate the girls but they couldn't. It was like these girls had a grudge they have been keeping against them and were ready to unleash it today.
"Stop fighting yourself now or you all will be eliminated from the competition before you even have the opportunity to start!" Just those words stop them in a second.
They all stood up from the girls.
"To the principal's office now!" Mrs. Han shrieked.
The students already disperse the moment they hear the teacher's voice, they don't want to be in trouble with her.
At the principal office, you can all students as kneel in front of the principal, the principal was shocked at what happened, these kids are the children of the top business tycoons and socialites, and these kids have never involved themselves in a childish fight so he was confused with what to say to them. 
"I want you all to call your parents now." The moment he said the kids began to beg the principal not to do that except for Mary and Jina. 
Mary has never invited her parents to school because she doesn't want the whole school to know she is a Yoon, even when there are parties she doesn't tell them, since her siblings were in the same school as her, they come and cover for them all without the students knowing it.
Even after much pleading, they were not able to convince the principal with defeated looks they began calling their parents one after the other including Jina, who burst into tears the moment her mum picked up her call. 
The only person who didn't call her parents was Mary. She was still kneeling, not moving an inch. She knows her dad already knows what happened, his eyes are everywhere.
"Mary Kendrick, you are the only one who hasn't called your parents." The principal called out to the girl when he saw she hadn't moved or even brought out her phone to call her parents.
"He knows already, there is no need to call him," Mary told the principal, still not moving.
" What do you mean by…." He stopped when he heard a knock on the door, he told the person to come in. 
There stood the minister standing there annoyed looking at his daughter with disappointment. He noticed her daughter changed a lot when she began her friendship with the so called Mary she always mentioned.
"Good day sir, you may have your seat while we wait for the rest of the parents." Just as he finished talking, two mums rushed in, they were Yeol and So min mums. They rushed to their kids and checked their bruised faces, getting annoyed. They asked who caused it and they both pointed to Trina and Ji Soo.
Soo min looked down, embarrassed by the look her father gave her when Yeol pointed to her. She knows she is in deep trouble.
The other parents also came in, including Clara Park. She was so mad when her daughter called her when she got to the principal's and saw Mary there she was shocked. Mary isn't the girl who caused trouble; this must have needed them to defend themselves.
"Who is the little brat who hurt my precious daughter this way?" Hannah asked, touching her daughter's face, and wiping her tears. Jina pointed to Mary who wasn't even looking at her. In an instant Hannah was in front of Mary giving her a slap and another resounding slap, making the parent and students gasp.
"Why the hell did you do that?" Clara yelled in shock.
She knows Yoon Ji Hoo won't be happy about what just happened even when Mary behaves rudely to him or her mum none of them has ever touched her, they would rather correct her than touch her. You might think they spoil her too much but they don't care. If she had done this to any of his sons he wouldn't have reacted to it. But this is his last baby we are talking about. He is going to hunt down the person who touches his baby even if it's to destroy the whole city. He even accepts his daughter's wish of not allowing people to know she's a Yoon. He might be cold to the outside world but he cares deeply for his kids. 
"Are you asking me why the hell I did that? You can see how she hurt my daughter and now you are asking me a silly question? She isn't even related to you why are you so worked up?" Hannah shrieked.
"I hope you don't regret what you just did," Clara muttered and sat down.
"Says the manager who was lucky enough to get a rich man into her pants," Hannah announced making the whole students gasp again.
"What did you just say?" Clara asked, standing up infuriated by what Hannah just said.
Not long after they heard a knock on the door, the principal told the person to come in.
There is a handsome looking young man putting on an ironed brown two piece suit with his glasses on and his hair gelled back walking in.
"Good day, may I know who you are?" The principal asked, almost shaking, this man screamed money. The students and parents looked at him stunned. The only person who didn't care was Mary, Clara, Trina, and the minister.
"I am attorney John Hyun and I will be representing Mr. Kendrick's daughter, he is busy so he won't be able to make it," The man replied coolly not even noticing the way he is being stared at. Clara smirked when she saw this Ji Hoo knew every single thing that happened now and is going to take a dangerous step if they don't comply. Wow, what a great technique.
The students and parents were shocked when they heard the name of the man before them. He is the world's best international attorney, no one could win him in a case. He isn't someone who can be called out immediately because he is damn expensive, how the hell was Mary's dad able to call him within the few minutes they were in the office. What surprised them most was that Mary didn't call to inform her parents what had happened. 
"It hasn't gotten to calling of an attorney, why would her dad call you?" The principal asked dumbstruck with what he just heard.
"We got to know Miss Kendrick here attacked your daughter first because she keeps bullying her friends and your daughter miss…" he stretched his hands to her gesturing for her to say her name.
"Jina," 
"Miss Jina's friends then attacked her sitting on her and hitting her badly when Miss Mary's friends couldn't stop them they pushed them down but Miss Jina's friends attacked them and Miss Mary's friends fought them back for self defense." 
"Are seriously hearing yourself right now?" Hannah yelled going berserk.
"If you didn't attack my client she would have paid for a fine but since you attacked her why don't we settle it gently right here?"
"You must be sick! I will take this to court." Hannah yelled again.
"Miss you seem to be forgetting something, my client hurt your daughter but a single bruise wasn't left on her, now look at my client's face." 
He pointed to Mary's face and the students gasp when they saw the hand print formed on Mary's face also a little bruise formed on the other side of her face caused by the ring Hannah wore.
They all looked at Jina and not a single bruise was on her face. Mary learned Judo. She knows the rules, she only gave a few punches on her tummy, her hair was what she dragged, and she knew her scalp would be in pain now.
"But!"
"Do you still want to take this to the court?" The attorney stopped her from saying anything, he can't continue wasting his time with her. He is a busy man.
Hannah was lost for words and couldn't say anything, she finally succumbed to him, and with a defeated face she sat on one of the chairs. The minister was appalled with what just happened, he wondered who was the father of this child even without moving a foot from the office everything was settled.
"This is a document you all need to sign." He said bringing out a file for each of them.
They all know what this attorney was capable of and with the way Hannah gave a defeated face they have no more things to say. So they all signed the document including the minister.
"All videos have been taken down but if anyone still does anything funny, it might not be to your advantage since you all already signed this." He finished his statement and gestured for Mary to stand up.
