(Y/n/n means (your nickname) for those who don't know.)

Y/n was no stranger to the world of the supernatural.

She was adopted by Charlie Swan and raised along with her sister, Bella, from a very young age.

So when Bella started dating a vampire, and their childhood friend Jacob turned out to be a shapeshifter, it was hard to ignore the existence of supernatural beings.

Y/n and Jacob have been dating for over two years now, since their first year of high school.

Now, on her 16th birthday, she, the Cullen's, Jacob, and her family were celebrating at her home in the yard around the back.

Charlie stood at the grill, barbecuing. Alice had her phone connected to a speaker for music. String lights hung over their heads, casting a warm glow down on them.

The sun was setting, low enough to not cast direct sunlight, for the Cullen's sake.

Y/n and Jacob swayed in each other's arms, along with a few of the other couples present.

He held her close by her waist, her right hand holding his left, with her left arm draped gracefully around his shoulders.

The event wasn't very formal, but Jacob wanted to dress up a little for his girlfriend's sake, so he wore a white button-up dress shirt and jeans. The top few buttons of the shirt were undone, revealing the top of his toned, bare chest.

His muscles made the shirt tight around his shoulders and biceps, but Y/n wasn't complaining. He made good eye candy.

"Happy birthday," Jacob softly says, smiling down at her.

"Thank you," Y/n replies with a grin, pleasantly looking back up at him.

Any fool who looked at the couple could see just how much they adore each other.

Y/n leans into his body, pressing her forehead to his as she sighs contentedly.

She had been so excited about today. Just earlier, she was boasting with enthusiasm, but now she seemed much more relaxed.

"You okay, Y/n/n?" Jacob asks worriedly, noticing her lack of energy.

"Just feeling a little hot," she murmured, closing her eyes.

"I can tell," he replies, leaning away from her face and taking her hand.

Her skin was increasingly warm, which concerned him. "Y/n?"

She only hummed in reply, not having the energy to use actual words. And with that, her body fell limp in his arms. She fainted.

"Guys!" Jacob yelled, getting everyone's attention as he moved to carry her bridal style. "Y/n is having a heat stroke!" he informs them in a panicked voice.

Alice pauses the music.

Carlisle is there within a blink of an eye as Jacob laid her down on the grass.

Bella and Edward join them.

"How? We live in Forks?" Bella asks, frowning down at the unconscious girl.

"I don't know. The only time I've seen this happen was when-," Jacob stops himself from continuing his sentence.

Edward, who had been reading his mind, asked, "Are you sure?"

Jacob looked up at the vampire, still not used to his 'gift'. "I don't know."

"What? What do you think it is?" Bella asks, looking between them with wide,  concerned eyes.

"You think she's like you?" Carlisle asks Jacob calmly, having had used what little context he has on the situation.

"I had the same thing happen to me when I first transitioned into a wolf. On my 16th birthday..."

"You should call your father," Edward suggests. "He'll know more about what to do than we would."

Jacob quickly reached into his back pocket before pulling out his phone and searching for his dad's contact information. He held it to his ear as he impatiently heard it ring.

"Jacob, I'm sorry. I know I'm late. I'm-," Billy Black excuses as soon as he answers, only to be interrupted by his son.

"Dad, Y/n's passed out. I think she's a shapeshifter because she's burning up and the timing," Jacob stresses to his dad.

"Okay. Okay. Calm down, son. Look at her arm. Do you see a tattoo?" Billy instructs.

Carlisle, who had heard his words with his super hearing, lifts up Y/n's sleeve to reveal a large tattoo along her shoulder. Almost identical to Jacob's.

Carlisle shares a look with Jacob knowingly.

"What the hell?" Charlie yells, making his presence known. He stands next to Jacob, looking down at his unconscious daughter's shoulder.

"Woah, woah," Bella starts, standing between Charlie and Y/n with her hands on his arms, preventing him from getting any closer. "Dad, let's just relax, okay? Edward's dad is looking after her. Let's head inside to give them some space, okay?" she suggests nervously.

"I need a beer," Charlie sighs stressfully, clearly not knowing how to feel about Y/n's ink as Bella leads their dad inside with Edward.

"Yeah, she's got the tattoo," Jacob speaks into the phone with a sigh.

Billy hangs up, causing Jacob to frown. A truck pulls up a few yards away.

Jacob runs over to the truck and speaks to his dad through the driver's side window.

Y/n starts to blink a little, having spots in her vision.

"Just relax," Carlisle soothes as she closes her eyes again with a sigh.

The rest of the Cullen siblings watch from afar, not wanting to interfere.

Billy looks at the girl, seeing her state through the window despite being far away. "Her biological parents must have been part of our tribe before they had passed. It's the only logical explanation," he tells Jacob.

"So, she's one of us?" The boy asks, suppressing his hope.

"Yes, son. She's of age. It should only be a few minutes now."

At those words, Jacob races back to his girlfriend's side, noticing her beginning to sit up. "Y/n!"

"Jake," she looks up at him, noticing the panic in his eyes. "What's wrong?"

"You-," he starts, think about how he should phrase his next sentence. "You're a shapeshifter. Like me."

She stands, with Carlisle's help, and frowns at her boyfriend. "I'm a shapeshifter?" She repeats.

Jacob nods in reply.

"I'm going to turn into a wolf?" She questions, running a hand through her hair as she processes this newfound information.

"You guys should probably head inside," Jacob warns the Cullen's, holding Y/n in a tight embrace. "She's going to need the space."

She holds him close as she hears footsteps on the grass fade away. "What do we do?" she asks, leaning her head on his chest.

"Run."

She looks up at him with furrowed eyebrows. "What?"

He takes her hand and starts a quick jog, guiding her along with him. "Not away, Y/n/n. It's just easier to transition when you're already moving."

She starts to jog at the same pace, laughing as she gets a little further ahead of him, letting go of his hand. He chuckles, speeding up a little.

He's winning the race when she mutters a quiet, "woah."

He looks back just in time to see his girlfriend jump high in the air before landing on four paws, now in the shape of a large wolf, her clothes ripped and discarded around her.

Jacob stops his strides, now holding eye contact with the wolf. She takes a few steps back cautiously.

"Hey, don't be afraid, beautiful," Jacob assures her, pacing up to her. He pets her nose up to her head comfortingly. "Everything's okay, babe."

He reaches behind his head and tugs his shirt off, holding it out for her. He respectfully looks away as she returns to her human form. She gives him a quiet "thank you," as she takes the shirt from his hand.

She tugs it over her head, tucking her arms into the sleeves. The shirt is huge on her and hangs like a dress. She smiles at her now shirtless boyfriend before hugging him from behind. "This is so cool!" She grins.

He chuckles at her words, turning around in her grasp before holding her closer. "Quite the birthday party, hug?"

"Best one yet," she replies, pridefully, leaning her chin on his chest as she looks up at him with the widest smile Jacob has ever seen.

He begins to guide her inside. "So, um, listen. I know this is really out of the blue, but since you're a wolf now and all, it's kind of customary for wolves to stay with their pack..." he trails off.

"Are you asking me to move in with you?" She asks, raising a brow at him.

He huffs a sheepish smile. "Yeah, I guess I am."

"If you can convince my dad, then sure. I'm all yours." She leans into him as they approach the house.

Once they returned, everyone was very happy for Y/n and Jacob.

Alice resumed the music as Y/n, and Jacob waltzed, Kissed & hugged through the night, happy to be sharing their big shapeshifting secret.
