By definition, Stiles and Y/N were friends with benefits.
They both may have had feelings for each other that they kept on the down low, but they loved each other. The whole pack knew of their feelings for each other and they also knew of the friends with benefits thing they had going on, but they just figured it would eventually push the two into an actual relationship.
The relationship would've happened if the Ghost Riders hadn't rode into town and taken Stiles, erasing all memory of him from everyone that loved him. After a long ordeal of dealing with the Ghost Riders, Scott, Lydia, Malia, and Y/N figured out a way they could find their memories of Stiles. Well, technically Lydia figured out a way to remember Stiles.
They needed to open a rift like Sheriff did when he remembered Stiles. The pack didn't know how, but as always, Lydia figured it out. Lydia decided the pack should try to use the machine that cools Parrish down when he's recovering from his Hellhound moments to put them in a trance-like state and open their subconscious where all the memories of Stiles would be. There was no way Lydia and Y/N would go in it because they were both human, but Malia and Scott went inside. Scott was the first to remember Stiles, but nothing happened. Malia and Lydia remembered him and a rift almost opened, but not enough to get Stiles back.
Finally, it was Y/N's turn. Saying she was scared to try and remember him was an understatement. All she knew was that she loved whoever Stiles was. "Y/N, you have to try." Scott sighed. Y/N sat on a stool next to Lydia. "In every memory I had, you two connected. It was a connection like no one else had with him."
Y/N looked over at the werecoyote who was standing next to Scott but looking down at her boots. Her face had a look of hurt and sadness planted on her features. Everyone knew that Malia loved Stiles, that she always would, but everyone also knew that he felt stronger for Y/N than he ever did with Malia. Malia looked up as a single tear slid down her cheek and then nodded. "He's right, Y/N. I saw it, too."
"So did I. If anyone's bringing him back, it's you." Lydia nodded, a smile on her plump lips.
"Do you really think it's our best shot at getting him back?" Y/N asked softly. The whole pack nodded, smiles on their faces. "Than I'll do it. For Stiles."
Lydia nodded, a triumphant look on her face. "We're going to put you in hypnosis just like we did with me."
Y/N took a deep breath, looking at the candle that Malia had relit. "Y/N, close your eyes." Lydia spoke softly. "Let your whole body relax. Let your fingers, your arms, your legs relax. You're in a field full of lilac flowers. Each flower you pick will bring you a new memory of Stiles."
Y/N suddenly found herself in a field of flowers, just as Lydia had said. It was a sunny and warm day. Lydia's voice continued echoing throughout Y/N's surrounding. "In order for you to remember Stiles, you need to pick a flower." In the field, Y/N looked around, deciding on a flower to pick, one that looked right. She walked to the small lilac flower, bended over, and plucking it from the ground.
A young Y/N strolled onto her new school playground confidently. Her pigtails swung through the air as her smile remained on her face.
"First day of first grade!" Y/N whispered happily to herself.
"Scott, that's not fair!" A small voice said from behind Y/N, but she paid no mind to it, continuing to pep talk herself.
"Don't be a sore loser, I just ran faster than you." Scott said proudly.
"Oh, yeah? Let's go again." Stiles said in a demanding tone. "On your mark, get set... go!" He yelled, taking off. Stiles looked back to Scott a smile on his face as he realized he was up ahead.
