The Fault Is Mine

Prologue

Kurt sat in his calculus class trying desperately to understand what was going on and whether he was even in the right class. Don't get him wrong, he loved Dalton but the classes were so much harder and they gave twice as much homework, it was exhausting but it was worth it going to class in the morning without being afraid that someone is going to dump a cup full of frozen food colouring on him. He was still wary sometimes, flinching when he thought that someone was a threat, waiting for a blow, but it never came. Not here. Not at Dalton Academy.

He felt a lot safer with his boyfriend, yes boyfriend, he was still getting used to that himself. But it was nice. Nice to know that someone is interested in him in that way and that he is not a lost cause. Josh. He was amazing. The lead of the local glee club, the Warblers, and being honest, he had a beautiful voice. He understood everything that Kurt was going through, helped him get over what Karofsky did to him. And most importantly, he didn't judge him when he found out that his first kiss was his bully. Josh was perfect and Kurt really felt like that they had something special.

But then the teacher suddenly clapped her hands very loudly making everyone look up from their books. Kurt's attention snapped away from Josh and he looked up to see someone standing next to her. Not just someone. The most gorgeous boy that Kurt had ever seen. His hair was dark, so dark that you could barely see where the light was falling on the obvious whole bottle of gel that kept it glued down to the boy's head. The first thing Kurt thought was why he put so much hair gel in and how would his hair look without it but he stopped himself by repeating one name in his mind. Josh. Your beautiful, hot, talented, perfect boyfriend. But he still didn't take his eyes away from the boy standing silently, awkwardly in the middle of the classroom. It was obvious that he was uncomfortable, maybe even a bit panicky, eyes darting around the room and warily eyeing the students, with his head slightly tilted down, but Kurt could see since there was no hair covering his eyes. Also, his eyes. Kurt was in the middle row and it was hard to make out the details, but he could see that his eyes were a dark colour and were very expressive. He could also make out the long eyelashes than almost reached the triangular furrowed eyebrows.

The boy was new, anyone could tell and it wasn't just because no one had ever seen him before but because he wasn't even wearing his uniform yet. He was wearing blue jeans and a plain grey shirt. Not Kurt's first choice of clothing, far from it but at least the outfit didn't clash, which was good enough. Kurt learned to accept that not all people thought that clothes were as important as Kurt did. That included Josh, no matter how much Kurt kept telling him that these shoes didn't match with this shirt, he ignored him and continued wearing his terribly matched clothes. Kurt didn't mind, though, he liked Josh not because of his clothes but because of his amazing personality and incredibly good looks. To Kurt, people expressed their personality through their clothing choices and judging by his clothes, this boy had no personality at all.

Kurt was once again snapped from his thoughts when Mrs. Connors spoke up in her rude tone. "Do you want to maybe introduce yourself or are you going to just stand here?" God, how he hated this woman. She had every single factor that kids hated in teachers and maybe she knew what she was doing but Kurt really thought that the point of being a teacher was to encourage students, not put them down constantly. He felt, even more, anger towards the woman when he saw the boy flinch, it was barely there but Kurt noticed.

The boy cleared his throat, "Blaine." He said. That was all he said. His voice scratchy, either from not being used for a long time or being used too often, Kurt couldn't tell. But judging by the moment, he guessed it was because he didn't speak much.

"That's not how we introduce ourselves here, young man. I know the principal told you everything about the rules and expectations we have here at Dalton Academy and I know that this is one of the first things she would have told you." Not she looked pissed. It was like the person who she was talking to ruined his whole life. Kurt couldn't understand how one person could contain this much anger within themselves. But what he couldn't understand more was that how could she let it all out of the boy who looks petrified of just being here. Kurt really felt sorry for him, this is probably the worst class to start the day with not to mention coming in for the first time at a new school. "But if you are not bothered enough to listen to the instructions on your first day here, I'm going to repeat it for you. You come into the class, apologize for interrupting, which you didn't do, then you introduce yourself to the class, full name, and say three things about yourself. Understood? Try again." She stared pointedly at Blaine. Instead of apologizing, which was unnecessary in Kurt's eyes since Blaine really didn't do anything wrong, Blaine just stood there, cheeks red and both hands clutching desperately at the notebook against his chest. It looked like he was taking controlled breaths because his chest was heaving. "Just Blaine." He whispered, eyes begging desperately to let him be.

The whole class, including the teacher, had their eyes on Blaine, who stood frozen in one spot. He obviously wasn't enjoying all the attention that he was receiving. The class was silent for a minute or two before Mrs. Connors spoke up again, sounding angrier than she did before, "How rude of you, Blaine. Go sit down, I'll talk to the principal later, we'll see what to do with you."

Blaine's eyes widened and with a quick "I'm sorry" ran to the only empty desk in the back corner of the classroom. He put down his notebook and held his pen in his right hand that was trembling violently. He was looking at the desk, refusing to look at anything else. Kurt wondered what had happened to make him freak out like that. It couldn't just have been the teacher being angry with him, but Kurt didn't know his backstory, the boy looked like he had a hard life and coming to a new school could've triggered the current anxiety. Even though Kurt didn't know him, anything about him, he couldn't help but feel sorry for him.

Blaine looked up and made eye contact with Kurt which made Kurt realise that he was still staring at him when everybody else went back to work. Kurt gave Blaine a reassuring smile and turned back around. There was something about the boy that just made him want to get to know him. He wondered who he'd be rooming with. The boy looked like he didn't have any friends, but Kurt wasn't quick to judge. He decided that he would try talking to Blaine after the class finishes, he would like to know more about this boy, whether Josh liked it or not. It's not like he couldn't have any other friends, right?
