Sterek One Shots

We're Just Friends!

"But why does he get to go?!" Theo whines as he and Stiles are driving back from the mall, Stiles' security guard in the backseat.
"Because he's my boyfriend? We've been together for 6 years now, who else would I take as a date?" Stiles asks, knowing exactly what Theo was expecting. Theo tolled his eyes and stared out the window.
Stiles shakes his head and groans to himself. He was invited to the AMA's with a plus one. He wasn't even up for an award, but he was the hottest fresh face right now and they wanted him there, and Stiles couldn't think of anyone else to bring to his first big award show. Stiles didn't bother furthering the conversation, knowing Theo was upset and jealous, clearly pissed that he can't be Stiles' date.
You see, Stiles met Theo back in the 4th grade. They were 10 years old and they fell into the same friend group, and Theo quickly became Stiles' best friend, besides Scott that is. They all stuck together as time went on, and once they reached high school it became painfully obvious that Theo's feelings for Stiles were not strictly platonic. Then when Stiles met Derek in 12th grade, Theo was not happy. When they started dating just before homecoming, Theo saw red. Of course, he tried to hide how he felt from Stiles, but it was too late, Stiles had figured it out long before, just not to Theo's knowledge.
Things only seemed to get worse when Stiles started stepping into the spotlight. While in University at UCLA, Stiles began posting some videos of him singing and it snowballed from there. His videos went viral, celebrities were giving him shout outs and wanting to do collabs with him, and the next thing he knew, the day after his graduation he was being offered a record label. Derek nearly fainted when Stiles got the call as they were cooking breakfast in their small apartment kitchen.
As Stiles' career took off, and he and Derek were being seen in the spotlight more and more often, it seemed like Theo was trying more and more to get Stiles' attention. The group of friends that consists of Stiles, Derek, Scott, Isaac, Kira, Lydia, Jackson, Ethan, and Theo, would hang out a few times a week, usually getting take out or watching movies, and Theo would always try to get in between Stiles and Derek, no matter what it they were doing. He would steal the seat next to him, or offer to pay for his dinner. It drove Stiles crazy, which meant it drove Derek completely nuts! It made Derek feel like he didn't exist around Theo, or that Theo didn't respect Derek or Stiles enough to back off, that and he was just purely jealous that someone was still trying to steal his guy. That's what made Stiles feel awful, that Derek was so jealous.
Stiles tried his best to reassure Derek that he was the only one that Stiles was interested, and that all of Theo's attempts were pointless because Stiles only had eyes for him, but it was still the topic of many arguments between the two.
Stiles even began reaching out to the other friends in his friend group who were just as annoyed with Theo as he was. He asked for their help to try and keep Theo away whenever they were all together, but damn he was persistentt.
Stiles was out of ideas; he loves Derek with every inch of his being, and he wants to marry and start a family with him. Theo has always been a great friend, but Stiles has made it very clear that he's not interested in him beyond their friendship. Stiles was lost, he didn't know how to keep both people happy without hurting either of them.
Theo mumbles a small thanks as Stiles drops him off, Thomas moving up to the passenger seat afterwards.
"Well that was awkward." He says and Stiles nods.
"He's just-he doesn't get it! I'm with Der! I'm beyond happy! I want to marry Derek! I can't see myself loving anyone else besides Derek!" Stiles groans and Thomas shakes his head.
"You've just gotta tell him that!"
"I've tried! I've tried making it obvious! But besides me physically shaking him and yelling 'I don't like you like that, leave me and my boyfriend alone!', I don't know what else to do!" Stiles sighs.

A week later, the group of friends is out at the club. Stiles offered to be the DD, and of course since Stiles wasn't drinking, neither was Derek, or...Theo.
"So how was the show? Looked like fun." Lydia asks and Stiles smiles at her.
"It was a lot of fun. We got to meet some awesome people, Der got the picture with Harry Styles that he's been dying for." Stiles smirks as Derek nudges him with a blush.
"WHAT?! You met Harry Styles?!" Scott gasps and Isaac rubs his back as he takes in this information.
"He was great! Amazing guy, really!" Derek smiles and Lydia groans in jealousy.
"I would've loved to be there." She pouts.
Stiles sees Theo roll his eyes, likely thinking no one was paying attention.
"Who wants another shot?" Jackson asks and Theo throws his hand up.
"Thought you weren't drinking?" Ethan asks confused.
"Changed my mind." Theo responds.
After a few more drinks, most of the group heads over to the dance floor, leaving Derek, Stiles, and Theo at the table.
"I'm gonna run to the washroom." Derek says with a kiss to Stiles' cheek.
Theo makes a gagging noise and Stiles sighs, annoyed. Derek shoots Theo a dirty look before turning to leave the table.
"What was that?" Stiles asks a clearly tipsy Theo.
"What? I didn't do anything." Theo shrugs.
"Derek is my boyfriend, and he has every right to kiss me. You can't be doing that." Stiles says very sternly.
"Well he stole my seat at the AMA's, and he stole my Stiles." He hiccups.
"I wasn't going to take you in the first place, and he didn't steal something you didn't have in the first place! Theo, you're a great friend, but Derek is my soulmate." Stiles raises his voice.
"But I looooooooove you!" Theo whines and Stiles shakes his head.
"I can't-" he throws up his hands and walks away from the table. He finds Derek coming back from the bathroom and grabs his hand.
"Come on, let's get out of here." Stiles sighs and Derek looks confused.
"What? What happened? I was gone for two minutes!" Derek asks and Stiles gives him a look that explains it all.
"Yeah, let's go." He nods and they head for the door.
•••••
The next time Stiles sees Theo is the next night. Him and Derek are cuddled up in bed, very peacefully sleeping after a long day, when there's a pounding at the front door.
"Who the hell is that?" Derek mumbles, eyes still closed tight and half asleep.
"No idea, but if they got past the doorman at this time of night, I'm gonna kill the doorman." Stiles groans as he rolls out of bed and heads for the door.
He uses the peephole and sighs when he sees who it is. He hits his forehead off the door before reluctantly unlocking it and opening it.
"Hey man! Took you long enough." Theo smiles and Stiles frowns.
"Theo, it's two in the morning. What the hell are you here? It's absolutely pouring outside, and I was happily asleep." Stiles groans.
"Well I just got a new video game and was wondering if you wanted to play it with me?" He says with a smile and Stiles takes a minutes to comprehend what his friend is saying.
"You came over, in the middle of the night, to see if I wanted to play a game with you?"
"Well no one else was answering, and I like playing them best with you."
"Look, thanks for the offer, but Derek has to be up early for work and I don't want to keep him up. Plus I had a super long day and I'm tired too."
"Well we could go to my place. But my couch isn't real comfy, but my bed is more than big enough for the both of us." Theo suggests and Stiles shakes his head.
"Goodnight Theo." Stiles says closing the door on his friend.
•••••
"Stiles, you've got to do something about Theo. This is getting ridiculous! He keeps showing up in the middle of the night! I don't know if he's trying to annoy you into agreeing to date him, or annoy me into breaking up with you, but I don't want either to work." Derek sighs as they wash the dishes from their dinner.
"I know Der, I know. But anything I say to him doesn't get through to him. I've got an idea, and I didn't want to use it, but I think it's the only thing that's going to help. It involves my show in a couple weeks and inviting everyone to come along so it doesn't seem like I'm just targeting him. Haven't worked it all out yet." Stiles sighs and Derek nods.
"Is it mean?" He asks and Stiles shrugs.
"Maybe? But I need him to stop! And if this is the way to get him to, then it needs to be done."
•••••
"Hey guys! Just wanted to let you guys know that you're all invited to my show next week if you want to come. Should be a good show." Stiles says the next time they're all together.
Theo's head perks up at that, and he smiles brightly.
"I'll be there!"
"Will we be VIP?" Lydia asks and Stiles rolls his eyes but laughs and nods.
"Yes Lydia, I've already arranged it."
"Great! Then I will gladly be there!" She smiles and the rest of the group agrees.
Stiles shoots Derek a look and he looks pleased.
•••••
The night of the concert, Stiles feels like his skin is buzzing and he hopes Theo doesn't completely hate him after this.
They're basically at the end of the set, and Stiles smiles down at Derek from his seat in the front row.
"Okay! So we've got two songs left of our set tonight! Now this is a song I'd like to dedicate to a dear friend of mine. They've been by my side for 14ish years now, and before anyone starts thinking anything, no, it's not for Scott!" He says with a slight smirk as he cues the band to start playing.
