Destiel High School FanFiction

Confused

When Dean got home, he saw that his father had left again. Typically. He went upstairs, showered and changed into his own clothes. He putted Cas' shirt under his pillow so he could have it with him when he sleeps. Hopefully Cas wouldn't ask for it back soon. Then Dean went over to his brothers room and knocked carefully.
"Sammy? Are you awake?"
"Yes."
Dean went into the room and saw his brother standing at the window.
"Are you mad? Because of yesterday?", Dean asked.
"What? NO! You didn't do anything wrong! I knew you were going to that party and I was totally cool with that. I tried to tell Dad the same thing, but .. well you know what happend."
"So you're not angry with me?"
"No, Dean. I'm not."
"Good. Then grab your things, we're gonna get breakfast at Renwick's"
"Really?", Sam asked excited.
"Yeah, Dad left some money here."
"Awesome!"

After Dean and Sam had a good breakfast at a diner near by, they went to school. Dean was a little bit afraid to see Cas again, but as long as Lisa was with him, he was sure Cas wasn't going to try talking to him. He found her in the hall on their table. She was probably waiting for him.
"Lisa!", Dean shouted through the hall so she could hear him. She didn't, but only because she had headphones on. On his way to Lisa, Dean was stopped by Cas.
"Dean we-"
But Dean ignored him and walked straight on to his girlfriend. He didn't know why, but he didn't want anyone to see him talking to Cas here. Still, Dean couldn't other but notice that the red sweater Cas was wearing today, looked amazing on him.
Lisa recognized Dean and took off her headphones.
"Hey, babe.", she said.
Dean kissed Lisa and sat down extra closely to her. He was disgustingly flirting with her, only to see if it would bother Cas.
-
"He's only doing this to make you jealous.", Kevin said.
"You're only saying that because of Lisa."
"Yes. But still. A straight guy doesn't just walk around kissing people because he's devastated."
"I have to agree with Kev on this one.", Charlie said.
"On the party he seemed like he had been searching for someone and then he asked me where you were."
"He did?", Cas asked with his eyes wide open.
"Yes he did. He seemed sad that you weren't there."
"That's also what he said to me yesterday night...", Cas said with a little sadness in his voice. He didn't get this whole thing. First, Dean kisses him like this, and on the next day he's sitting there making out with Lisa and ignoring Cas like nothing had happen.
"But hey, at least he won't be able to ignore you later in Chemistry", Kevin said to cheer Cas up.
Kevin was right. Cas would not give up that easy.
