When Y/N came home for the summer she was all up for staying home and doing absolutly nothing, but that didn't happen. She was playing taxi survise, driving her little brother to and from places, it wouldn't have bothered her if he didn't have to go somewhere every other hour.
"Stiles I swear if you're just going to use me as a taxi all summer I'm gonna throw out your Staw Wars movies." Y/N threatened her brother over the phone. She was seriously about to kill him, she was home to help out her dad, not be her brothers damn choffer.
**
Pulling up to the building Stiles was supposedly in she had to douple check to the address Stiles had given her. There was no way this was the right place. Calling her brother she groaned when it went to voicemail, she tried a couple more times before getting frustrated and walking into the building.
"I'm going to kill him." she muttered to herself while calling Scott, if her brother wouldn't answer her phone maybe his best friend will. When Scott didn't answer she finally just walked into the loft.
"Where the hell is Stiles?" She asked, looking between Scott and this other man, clearly have interupted their conversation.
"He went with Malia. I thought he called you." Scott explained.
"Wait, who the hell are you and why the hell are you here?" The other man asked, his voice showing his annoyence.
"I was told that my idiot brother was here and I was supposed to pick him up."
"You're Stiles older sister? There's no way you two are related." He was going to continue but Y/N was not in the mood to deal with anyone's bull shit today.
"I don't know nor do I care who you are, but I'm going to leave." she started to walk out before turning to Scott. "And Scott, if you see Stiles before I do tell him I'm going to kick his ass."
*
As Derek watched her walk out he couldn't believe that she was related to Stiles. She seemed like she could kick his ass, and he would gladly let her.
"You might want to mop up your drool off the floor, someone might notice." Scott joked, hearing the increase of Derek's heart
"Shut up." Derek growled.
*
When Y/N walked into her house, she was annoyed, pissed, and slightly hungry; driving Stiles around didn't give her a chance to eat much. In the middle of microwaving last nights leftovers she heard the door close.
"Stiles?" She called out, not knowing if her father had gotten off of work early today.
"Yeah?"
"I'd just like to thank you for making me drive around just to see that you left with your damn girlfriend and I got to meet an asshole." She let her sentance drip with sarcasim, showing her brother how pissed she was.
"I see you met Derek." His smug tone made her want to smack him a couple of times.
"I don't care what his name is, he was an ass and I would like to not meet him again."
*
A loud knock on their front door made Y/N roll her eyes, it was three in the afternoon no one should be knocking on the door. Looking through the peep hole and seeing Scott caused her to roll her eyes.
"Stiles isn't here." She exclaimed when she opened the door.
"I know, but I'm here to talk to you." He said, pushing past her to go sit on the couch. She would've been annoyed if she wasn't so tired right now.
"Why?" She asked, her mind realing with what he would want to talk to her about.
"Just thought you should know something."
"What."
"I just thought you should know that Derek's got a small, well maybe not so small crush on you."
Y/N was shocked at what he told her. The last time she had seen Derek he was a grade A asshole towards her, so the thought of him actually having some sort of feelings for her shocked her.
"There's no way Scott. He.... h-he" She started stuttering, trying to come up with a reasonable explanation to everything.
"I heard his heart. You can't hide the truth Y/N. Just think about it." With that he walked out of her house.
*
After a couple of hours of thinking Y/N found herself in the same loft where she had met Derek Hale. She would've never thought that this would ever happen. Someone like him finding interest in a girl like her.
"So.... I think we need to talk about somethings." Y/N muttered, but Derek heard it liud and clear. He could sence she was nervous. He knew what Scott had told her, and he knew there were two out comes to this.
"Yeah I think we do."
"Scott told me something earlier today and I wanted to know if it was true." She looked around, trying to avoid meeting Derek's eye. "Um.... he told me that you-"
"That I like you." He heard her heart pick up, matching his. "It's true, and I know that I was an ass when we met and I can't really justify that, but if you want to try maybe we could go out Friday night?"
Y/N just nodded; she didn't know if she would regret this down the road but one date couldn't be so bad right?
*
After that Friday night the one date turned into two and then they began a relationship. Y/N couldn't ask for a better boyfriend. He may have been an ass at first but once you get past that there is a loving and caring person under the anger and harshness.
Now five years later Y/N and Derek Hale have been married for four years, have two beautiful little girls, are living in a cute two story house in Beacon Hills, and neither of them would change anything about it.
"I love you so much." Derek whispered pressing kisses to her temple.
"I love you too Derek." Y/N pressed a kiss on his cheek and pushed closer into his embrace.
Thinking back on it Y/N knew that if Stiles hadn't made her drive him around everywhere she wouldn't have met her husband and she wouldn't have the family she had now. She'd have to thank him for that one day.
