“You know, it's rude to stare.” Sebastian stated from behind you.
You pulled your eyes away from the boys that stood far before you and looked at your older brother.
“I wasn't staring.” You replied. “I was just observing.”
“Well, then you were doing some creepy and rude observing.” Sebastian mocked. “Just go talk to him, Y/N.”
“No, no way. I'm not talking to him. He doesn't even know who I am.”
“You sound like you did when you were in high school.” Sebastian said with a shake of his head. “Just go up and talk to him. I mean, Tom's with him and you guys are friends aren't you?”
“But nothing. If you want Harrison to notice you, you just have to talk to him or make an ass of yourself like you always do.”
You gasped and playfully slapped your brother's arm. “I have never made an ass of myself!”
Sebastian arched an eyebrow and gave you a look, a devilish smirk on his lips.
“Oh, really? What about that time you tackled the school mascot-”
“Okay. What about the time you got wasted and projectile vomited-”
“You're the one who got me drunk!”
“Ugh, fine. What about the time you took a nose dive down the stairs and-”
“You tripped me and I broke my nose!”
“Quit making excuses!” Sebastian exclaimed.
“Quit getting me into trouble!” You replied.
“Just go talk to him! My god, Y/n, if you don't talk to him sooner or later I'll just tell him about the little crush you have on him.”
“Oh, but I would.” Sebastian remarked.
“But, you love me.” Sebastian chuckled. “I got to go film, but you have to talk to him. You just have to.”
“Why do you keep pushing this?” You asked with a raised brow. “Is there something I don't know?”
“You'll never know if you don't talk to him.”
“But I like admiring him from afar.”
“Y/N, you creep, just do what you're told. I'll see you later.”
“Bye, Seb.” You sighed, placing your chin in your hand as you watched Tom and Harrison joke around, debating on whether or not you really wanted to talk to them.
“Y/N!” Tom hollered, his voice pulled you from your train of thought.
“Come here!” He replied, motioning for you to come to where he and Harrison were standing.
You arose from your seat and ran over to them.
“Nothing much, Stan.” Tom said, wrapping an arm around your shoulders. “Harrison and I were wondering if you wanted to go get dinner with us.”
“Oh, I don't know, Tom. Sebastian said something about wanting to go get take out and watch movies with Chris and Anthony.” You replied, your eyes not on Tom, but Harrison.
“Come on, Y/N, we never hang out and you always hang out with the guys.”
“Well, yeah. Cause they're my brother's friends. I'm better friends with Chris than Anthony, but you know what I'm saying.”
“Can't you ditch the guys for one night and hang out with us? I want to get to know you better.”
You thought about it for a moment, you really didn't want to hang out with the guys and Tom and Harrison were good guys. You also thought about Sebastian telling you to talk to Harrison and not make an ass of yourself, but your stubbornness was definitely making you seem like an ass.
“Okay, fine. I'd like to get dinner with you guys.” You agreed. “Besides, it's not like the guy's will miss me that much. We hang out all the time.”
“I bet Chris will miss you.” Harrison spoke up.
“What makes you say that?” You asked, wondering why he was bringing up Chris.
The first time you're going to hang out with the guy you have a thing for is the first time he asks you about another guy.
“Well, you guys are dating, aren't you?”
You laughed. You laughed hysterically.
“What? Me and Chris? God, no! He's like my brother. Hell, he acts like my brother!” You exclaimed with laughter. “Me and Chris aren't dating.”
“Oh.” Was all Harrison had to say.
“I should go tell the guys that I won't be having dinner with them. I'll be right back.” You stated.
“I'll come with you. I need to talk to Sebastian about a scene were doing tomorrow.” Tom said, following you away from Harrison and towards your brother's trailer.
You two walked in silence before Tom spoke up.
“I know about your crush on Harrison.” He said softly.
“Let me guess, Sebastian told you?” He nodded. “Figured. He can't keep a secret to save his life.”
“Well, neither can I because I had to tell him a secret to get that secret out of him.” Tom explained.
“Well, what was the secret?”
“I can't tell you because it's a secret.”
“But you told Sebastian! And we have the same DNA, so we're like the same person.”
“I won't tell you the secret, but I'll tell you this,” Tom started, “You look at Harrison like he's the sun and he looks at you and thinks you're as beautiful as the moon and it's a fucking tragedy cause you both think the other is looking at the goddamn ground.”
You internalized Tom's words for a moment, too shocked to know how to respond as you approached Sebastian's trailer.
“Wait, so Harrison likes me?” You asked. “How? I thought he didn't notice me.”
“It's cause you both don't talk to each other! You're both a couple of pansies let me tell you.” Tom exclaimed, annoyed.
“Goddammit. I'm an idiot.” You shook your head before you opened the trailer door and climbed in.
Sebastian and the guys were seated on the couch in the trailer, all three looking at you expectedly.
“So, are you going to hang out with Tom and Harrison?” Sebastian asked.
“Yeah, how'd you know?” You looked between Sebastian and Tom.
“They're in kahoots.” Chris spoke up. “Come on, kid, did you really think this was all an accident? They've been planning this shit for a week.”
Sebastian jabbed Chris in the ribs with his elbow. “You weren't supposed to tell her all that.”
“Sorry.” Chris mumbled, rubbing his side.
“You guys should probably go, wouldn't want to keep that boyfriend of yours waiting.” Sebastian said.
You crossed your arms over your chest and blushed. “He isn't my boyfriend.”
“Let's go.” Tom said, grabbing a hold of your arm and leading you out if the trailer.
You walked in silence, lost in your own worlds until you made it back to where Harrison was waiting for you.
Tom coughed as you guys approached Harrison. “You guys should go ahead. I'm not starting to feel well.”
“You bastard.” You whispered so that only Tom could hear.
He stifled a laugh as he coughed again. “Yeah, I'm just going to go lie down or something. But, please go on without me.”
“That's an awful impression, mate.” Harrison said. “I thought you were an actor.”
You laughed as Tom's expression changed from a look of fake pain to a look of insult.
“Well at least I don't have a crush on a girl who I just got the guts to talk to today.” Tom countered before turning on his heel and running.
“Don't mind him, him and my brother are the reason we're going to get dinner now.” You said, looping your arm around Harrison's, a new found confidence washing over you.
“Hell yeah, we are. I didn't just go through all that to not go to dinner with you.”
“You're amazing.” Harrison said softly.
“And so are you.” You blushed. “Now, let's go before all the good places get busy.”
