We're 18 and Crazy 》Sastiel AU

Cas sat in his English class, tuning his teacher out. He already knew how to fix a run on sentence. He didn't need to learn it again.

His mind kept drifting to the boy he saw in the library. He didn't know who the boy was, but the boy obviously knew and hated him.

Cas wasn't that surprised that the boy knew him though, with his brothers being who they were and all. The only thing that did surprise him was the fact that the boy hated him. He's never talked to this boy once! He doesn't even know who he is!

What did I ever do to him? Cas thought as he scribbled in his notebook. Did I do something that I don't remember? Or did one of my brothers do something to him? That seems reasonable...

Cas sighed quietly and glanced at the clock on the wall, glad it was almost time for the class to be over. He started to quietly put his stuff away, noticing other students doing the same.

Less than five minutes later, the bell rang and everyone jetted out the classroom with their things.

Cas hurried down the hall, going to his locker. He resisted the urge to cringe again when he saw it. He threw his English stuff in his locker, then got his stuff for science.

With a sigh, he closed his locker and started walking down the hall to his class. He walked in and took his seat, sighing softly as he got ready to take notes.

Towards the end of the class, Cas got called to the principles office. He walked to Mr. Singer's office and knocked softly on the door.

"Come in!"

Cas opened the door and walked in. "Hello, Mr. Singer. You wanted to see me?"

"Yes, Castiel. Sit, please," he gestured to the seat in front of his desk as he spoke.

Cas sat down and folded his hands in his lap, glancing around the office before looking at Mr. Singer. "Is something wrong, sir?"

"Well... I've been looking at your grades and found that you're doing exceptionally well in all of your classes except for one. Calculus."

Cas looked down at his lap in shame. He had known that he wasn't doing good, but he thought that if he just pushed through it, his grade would somehow go up. Obviously he was wrong if the principal was concerned for his grades.

"Now, Castiel, I don't want you to fret, son. It's not the end of the world. Yet. You still have a few months to bring your grade up," Mr. Singer started. "I believe you can bring your grade up with a little bit of help. I was thinking of assigning you a tutor."

Cas looked up and opened his mouth to disagree, but didn't. He shut his trap again and just nodded.

"Your math teacher has told me that you have a test coming up soon. We'll see how well you do with this test before with assign your tutor, alright?"

Cas nodded again. "Yes. Thank you, sir."

"You're quite welcome, Castiel. You may go now."

Cas got up and walked out of the office. He started to head back to his class, but took a detour and went into the bathroom.

He walked over to a sink and sighed, splashing water on his face in the process. His head was hurting badly, signaling that he was about to cry. He thought about how if he failed his math class, he wouldn't get into the college he wanted. He wouldn't amount to anything in his life.

Before he could stop himself, the tears started falling; fast and heavy. Sniffling, he went into one of the stalls and locked the door. He sat on the toilet and put his head in his hands, crying hard.

He heard the bathroom door open and immediately stopped sniffling. He wiped his eyes with his shirt and stood up. He flushed the toilet for good measure, then walked out the stall and went over to the sink. He quickly turned it on and splashed water in his face.

As he was drying his face, he suddenly got shoved into the wall closest to him and gasped lightly. He looked at who pushed him and frowned when he saw the boy from earlier. "W-what the hell are you doing?! Let me go!"

"I saw you leave Mr. Singer's office," he started with a sneer. "What'd you tell him, huh? That you saw someone smoking in the library? Huh? C'mon, Cas, tell me what you told him!"

"I didn't tell him anything about you! I don't even fucking know you! How the fuck could I snitch on you?! And don't you dare use my fucking nickname, you ignorant fuck!" Cas yelled, his anger rising.

The boy smirked at Cas getting angry and dropped his arm. "Hm. We'll see. If I get suspended, your ass is dead." He stepped away from Cas and looked into his eyes, eyebrows knitting together. "Were you... crying?"

Cas didn't say anything. He didn't have to answer this boy.

"You were!" He laughed. "Wow. You're a pussy."

"Fuck you, you jerk! You don't know what the fuck's going on in my life!"

"Right, like you of all people knows true pain. What, daddy didn't buy you a new car?" The boy asked, before fake pouting.

Cas clutched his fist, but didn't do anything. "Listen, I don't know who the fuck you are, so I suggest leaving me the fuck alone..."

"Or what? You'd fight me? I'm so scared!" He laughed before walking to the door. "Do me a favor, would ya? Tell Lucifer, Sam says hi," he smirked before walking out the bathroom.

Cas frowned and furrowed his eyebrows. He knows Lucifer? I'm so confused... He sighed and ran a hand through his hair.

He waited a few minutes before walking out the bathroom, only one thing repeating in his head, Sam... Sam... Why does that name seems so familiar... I'm definitely asking Lucifer about him.
