Noblesse Awakening Rai x OC

What are the reasons?

It has been a few days since Shinwoo attempted to show off to Seira but instead, everything went surprisingly well in the end, and now Byeol has no idea if Rai is her boyfriend or is just having a fling around...could be the first option. Byeol wore her hair loose again as she continued to gather her things for the next class she felt a strange energy coming from outside and stopped what she was doing as she looked at both Seira and Regis's reactions they were as stiff as a board. Byeol followed behind Shinwoo and Ik-Han out of the class,

"C'mon let's go the other class is in another classroom!" Shinwoo exagerates.

"What's wrong guys? Aren't you coming too?" Ik-Han asked making both white heads relax a bit until one of them answered.

"Go ahead we'll be a bit late. Seira and I will catch up," answered Regis not turning his head towards the 3 friends. Byeol, however, knew something was up, and as soon as their friends were gone she asked, "Who's energy does it belong to?"

"..." Both of them kept quiet as they both exited the classroom through teleportation. Byeol narrowed her eyes in concern wondering if it could be related to Rai's coffin incident. "Well, better head to class then..." 

But that didn't stop there when she was about to head to class something told her to investigate the main gate and so she did. It took her a while to get down as she quickly glanced from the window to see both Seira and Regis kneeling on the ground in front of an elderly man with the same red eyes and characteristics of a noble just like both Regis and Seira the same white hair along with a black stripe on both sides of his head slicked back hairstyle along with his wrinkles spotted here and there he was even dressed sharply. He stood straight along with a walking stick and his monocle with an intimidating aura. 

"It is a privilege to see you again, Clan Leader," says Regis with a hand across his chest.

"Regis explain all this. Common sense dictates that the likes of these three should not be here." demanded the Clan Leader staring straight at his grandchildren.

"No, they're-" Regis begins to say as his clan leader cuts him off in disappointment.

"Regis, have you forgotten your pride as a noble?" he questions him making the boy flinch at his words as he continues, "Cavorting with these people such as these and neglecting your duty as a result..."

She couldn't believe what she was hearing from the old man who spoke like he was some boss or family member. Her suspicions went way overboard as she soon came to the last conclusion, 'Could that be his grandfather?' she thought as she met up with them she called out thinking she was saving them, 

"Regis!Seira! We're supposed to go to class right now!"

Everyone froze hoping that the elderly man wouldn't do anything to her but then something happened. "She is not supposed to be here either," it was the last thing the Clan Leader's eyes glowed as soon as he reached her mind Byeol suddenly felt someone inside her mind making her stumble backward and making everyone yell her name.

"BYEOL!"

Byeol's POV: 

I felt someone trying to erase this encounter as soon as he got close to my liking, I set up my defenses and yelled staring at him straight in the eye sweating. "Get out of my HEAD!" Now it was his turn to stumble backward but remained with his serious face.

Gejutel then narrowed his eyes muttering, "What are you?" as he made her float in the air by only 2 feet off the ground. Making Byeol smile a bit.

"My my what business do you have at their place of work? And I would appreciate it if you let my student go," said the Chairman as he smirked, a slight shock coming from the old man as he said in a low voice, "Frankenstein..."
