Taehyung was walking closely behind me as we walked towards my form group. The day hadn't even begun and I wanted to go home and hide in my bed. I kept feeling him staring at me and I gritted my teeth and stepped into my form class.

"Alright, you can stop talking now," I said and everyone went to their seats "Lucas if I catch you on the phone again, I will get you to read out to the class what you're writing,"

"Probably not a good idea," He said shoving his phone in his blazer pocket "I'm all ears"

I sighed "Class, this is Mr Kim. He will be your form tutor for the rest of the year"

"I'd prefer you," Jeno said, grinning at me "You're hotter"

His group of friends laughed and I lifted my eyebrow making them stop.

"Whether or not I'm hotter than him, he is your form tutor. But I'm not going anywhere just yet," I said "I need you to cooperate and do as he says. If you don't, then the next few lessons you have with me will be all exams. But not secondary school exams, university exams"

"That's not fair," Rose pouted

"Life isn't fair but if you all want to go into college and university then you will have to get used to that," I said smiling at her "Mr Kim will take the register so he can learn your names and Lucas, read out that message please"

Lucas' eyes went wide "How could you see that? You weren't looking at me"

"Up you come please,"

"Ah man," He said dragging his feet to the front "I'm going to get detention for this"

"Going to? You already have it" I said "Read it out"

Lucas went red in the face and cleared his throat before reading the message "Don't you think miss looks fit in that outfit? I think she should wear tight shirts more often"

I looked over at his groups of friends who were bright red in the face "Why don't you come up and read the rest of the messages Jisung?"

"I'd rather not," Jisung said, his eyes slightly wide.

"She told you to come up," Taehyung said "So, do as you're told"

The girls in the class all giggled and started whispering to each other about Taehyung and I carried on staring at Jisung.

Jisung sighed dragged himself up and pulled his phone out and turned to face Taehyung "If I was older I'd definitely bang her"

"Jesus," I muttered under my breath. I quickly glanced at Taehyung who was holding back a smile.

"Dude, have you seen how tight her ass is and how good her tits-"

"Ok," I said "Sit back down. Now"

"We are in so much trouble," Lucas said quietly.

"Let me teach you kids something about respecting women," I said folding my arms.

Taehyung stood at the front of my chemistry class teaching them. I sat at the desk watching him and making sure the class paid attention. When I knew they were working, I started marking some work. I listened as Taehyung answered questions and helped the class.

As much as I hated to admit it, Taehyung was good with the students. He was also very good at answering the questions they threw at him. I even caught the girls blushing and whispering about him. Not that it was a shock. Taehyung was handsome and he must have studied hard considering the university he had graduated from.

"Miss Yoon?" I looked up from my marking at one of the students "May I use the toilet?"

I nodded at her and she let out a sigh of relief. She grabbed her bag and rushed out of the classroom.

"Alright," I said getting to my feet "Who wants to tell me what a catalyst is?"

No one put their hand in the air and they were avoiding looking at me. I rolled my eyes and tapped one of the boys on the shoulder.

He sighed "Something that speeds up a reaction"

"Good," I said, "So, someone tell me four ways to speed up a chemical reaction. If no one puts their hand up, I will pick someone again"

A few people put their hands up and I pointed at the girl who was sat by Taehyung.

"Use a catalyst"

"Someone else," I said.

"Increase the temperature,"

"Another one"

"Increase the surface area of the reactants"

I smiled "Good. Now, who is going to tell me the last one?"

No one said anything.

"Ok," I said and looked at Taehyung "Mr Kim. What is the last one?"

He smirked "Concentrate of the reactants"

"Why?"

"Did you want the theory behind it?" He asked and the class sniggered at his answer "According to the collision theory-"

His words were cut off by my student coming back into the class.

"Um, Miss Yoon?" She said, "C-can I talk to you?"

I nodded "Alright class. You have earned a 5-minute break. You know the rules. Mr Kim, can you mark the second half of those papers please?"

"Anything for you," He whispered as he walked past me. I gritted my teeth and stepped outside to talk to my student.

"Um, can I, uh go home?"

I frowned "Why?"

"Well...you see, I, um..." She said and shuffled foot to foot "I've had an accident and I really need to go home"

"Oh!" I said, "Of course. Let me write you a note and hand it over to the receptionist before you leave. Do you need anything?"

Her face was bright red and she nodded "I don't have any pads on me,"

"Wait here," I said and I walked back into the classroom to grab my keys. Taehyung was watching me closely and I ignored him. The girl followed me towards my office and I rummaged through one of my drawers. I pulled a pad out and handed it over to her "Grab your coat and you can leave"

I wrote her a note and the bell rang. She thanked me and rushed off. I sighed and sat down hard on my chair. The door opened and Taehyung came in, closing the door behind him.

"I finally have you alone," He said.
