Derek was surprised when Stiles told the pack about his wish to leave and live with his aunt in Canada. Just because Stiles and Derek weren't exactly best friends or something he was sad to see him leaving. The boy is pack and pack is family. Nobody likes to lose his family, especially Derek, who has lost his parents snd sisters in the fire.

Stiles reassured that it wouldn't be the end of the world and that he would come back sometime in the future but Derek wasn't sure if he really would come home. Beacon Hills was full of creatures they had to fight and Stiles wouldn't have to do this somewhere in Canada.

Before Stiles left he wanted that they all promised that nobody would contact him until he was ready. All of them promised him and the boy hugged the whole pack, Derek was the last one and he could smell Stiles arousal. That is just lust. Derek wanted to reassure himself, the boy doesn't deserve anything broken like the former alpha. He didn't even know if Stiles likes boys too.

Deep inside Dereks heart he knew it was more than that but he ignored it.

A month after Stiles had left everyone was missing him but kept their promises. Some of them suffered quitely while others talked about it aloud. The most miserable was Scott and Derek could understand that feeling.

Derek himself felt something he couldn't identify. He was not sure if it was something physically or emotionally so he went to Deaton. The vet knew immediately what was wrong and told the beta that it was the distance. Derek was confused and Deaton must have noticed by his frowing and explained further "It's the distance. You are too far from your mate."

What?

"What mate? I don't have a mate." Deaton just shook his head and Derek left the vet irritated.

Meanwhile Stiles had found a job as underwear model. He never imagined to be a model because of his pale skin, his moles and skinniness. The boy enjoyed his job as well as living together with his aunt. But he was missing his pack, his family. It was his own fault because he made them promise no contact to him until he would make the first step. His father was calling him every sunday evening. The sheriff sounded exhausted and Stiles wanted to make sure that he wouldn't eat anything bad.

But then one day Lydia called him, telling himhow miserable everyone was. Stiles didn't promise her anything and since then he got letters and mails from the pack members. Sometimes there was a heart shaped box with chocolate or a bouquet without any note who sent it.

About a year after the boy had left BH he felt pain inside of him and a strong urge pulling him somewhere. After suffering the pain for a week Stiles gave in and let the feeling pull him away.

In BH had arrived a new threat while Derek tried to figure out the mate thing. There was a day when he found a picture of himself and Stiles from years ago. He remembered feeling this pain before, when he and Laura left for New York. Then he had thought it was because of the loss of his family but it had been about his mate the whole time.

Stiles was his mate.

The pack was sending Stiles things so Derek decided to send the boy something too. That was when Derek started to investing money in chocolate and flowers.

The former alpha woke up with a pounding head. He didn't know where he was until a familar person entered his prison cell.

"Kate."

"Derek. It is time to finish what I started."

The only thing Derek felt from now on was pain.

Stiles was on his way to BH, where else could the urge pull him, when Scott called him.

"Hey, we need you. It's important or I wouldn't call. Pleeeeasse come home?"

"I'm already on my way. I'll come to your house." Stiles ended the phone call.

Reaching the McCall household the boy could see the pack waiting. He jumped out of the car and asked "What is wrong?" But before anyone could answer, he knew. "It's Derek, am I right?" Surprised everyone nodded. "I know where he is. We have to hurry." The pain Stiles was feeling was increasing rapidly and Lydia seemed to notice. "Are you ok?" Gritting his teeth he answered "No, I think I feel part of the pain he feels." The girl was blinking at him as they sat in the backseat of Scott's moms car.

"I don't know why I can feel it but was on my way home before Scott called." Lydia looked shocked but said "But I think I know why. He was behaving so different since you left." The boy frowned. "He is your mate, that is the reason" Before he could answer they reached the old house. Derek was tortured and Stiles had to help him instantly. But Scott held him and said "We fight you take care of him ok?" Stiles nodded and followed him inside.

Derek was electrocuted and Kate was standing there enjoying his pain. Stiles couldn't contain his anger any longer, nobody would hurt his mate. Suddenly Kate was screaming and Stiles was smirking satisfied. While he was in Canada he finally learned how to use his Kate was the one who was suffering the electrocuting.

There was a huge fight but the boy knew his friends would manage it without his help so he ran over to Derek. "You hear me?" The man looked at him falling in his arms. "Shhhh, she is dead. Derek she can't hurt you anymore." Soothingly the young mage was stroking over the others back. " You are here. Why are you here Stiles?"

The boy held him even tighter "Because nobody hurts my mate without feeling my anger." Now Derek was looking into Stiles eyes stunned.

"How do you know?"

"We'll talk later. Let's get into the car so you can fully heal yourself." Stiles took Dereks hand helping him and at the same time he used a bit of his magic to heal his mate.

Derek was so exhausted that he fell asleep on Stiles shoulder on a ten minutes drive over to the sheriffs house.

"Dad, please no questions right now. We'll get Derek onto my bed at first." Stiles father was so shocked he just opened the door so that everyone could get into the house without saying anything.

Scott, Isaac, Erica and Boyd were carrying the asleep beta up the stairs into Stiles room without waking him up. The mage pulled a blanket over him. The five of them were walking downstairs into the living room where the rest of the pack was waiting impatiently.

"Sooooo, where do I start? Ok, I'm a mage and Derek is my mate as well as I'm his. Obviously Kate wanted to finish her business but I stopped her. Thanks for helping Derek btw." Stiles was smiling at his friends and is dad. "I'll go to him now. See you soon guys." All of them were looking after the boy climbing up the stairs.

Right when Stiles opened the door Derek was sitting up on his bed. "Hey, lay down again sourwolf." Stiles was walking over to the bed sitting down on his mates right side. Derek was trying to get up again so Stiles sat on him werewolf was blushing and Stiles found it more than adorable. "Are you better now? Or should I help you heal?" The boy wanted to know. Derek was shaking his head."I'm fine."

"No, no I know you are everything but fine, Kate nearly killed you. But I'm really glad she didn't. You know I haven't know about us being mates until we came to rescue you. You know I had a bad feeling, that was the reason I was on my way even before Scott called me. Since when do you know about this?"

Derek was quiet for a second before answering. "I felt a pain so I went to Deaton, who told me it was the distance and then I found an old photo an knew."There was something the other wanted to ask him but he didn't so Stiles demanded "You are not telling me something!" Derek frowned but replied anyway. "It's not fitting now but why underwear?" For a moment Stiles looked stunned but then he started to laugh hysterically. "Sorry but ... I don't really know it was ...randomly"

Nodding Derek pulled his mate down onto him and began to nuzzle his neck. "Thank you."

Stiles gave Derek a chaste kiss.
