"I can't believe you!" Stiles yelled throwing his arms up as he looked at his boyfriend of two years Derek Hale. Derek growled at Stiles his eyes changing color. "I saw you! He had his tongue down your throat!" He yelled getting angrier at the second.

"It wasn't me! I tried to push him away!" Stiles yelled. "Liar!" Derek yelled back. "Fine then! I don't wanna see you! We're done!" Stiles yelled turning around and walking away. "Fine!" Derek yelled back not looking at Stiles.

~3 months later~

Derek felt nothing but pain. He couldn't eat, couldn't sleep, couldn't even try and be with someone else. His mind always went back to Stiles. The way he laughed, talked, looked, smelled.

It was killing Derek and his wolf. Yet neither of them knew why they wanted only Stiles. So he went to Peter. Peter smiled and started to laugh after Derek told him what was going on.

"My dear nephew," Peter started. "You've found your mate." Mate? Derek's wolf held the word within his head. Mate...mate! Mate! He yelled. Derek felt his heart pick up as he shot from the seat and outta the house.

MATE!!! The wolf yelled as Derek ran faster to Stiles' house. As Derek got there he could hear Stiles. "I don't know Scott...I mean Derek didn't give me time to tell him I was forced into that kiss."

Derek looked threw the window to see Stiles' on the phone. Derek slowly knocked on the window. Stiles turned around and looked at him. Slowly he let Derek in. "Stiles before you say anything. I want you to know, I'm sorry.."

Stiles looked at him. "I didn't believe. And I'm really sorry for that." Derek went on. Stiles sighed, "it's okay Sourwolf..I know you where just mad so was I. I'm sorry too." Derek smiled and pulled Stiles into a hug.

"Stiles," Derek whispered. "I have something to tell you." Stiles looked at him. "You're my mate..." Derek wanted for the rejection, waited for Stiles to yell at him. But it never came.

Derek looked at Stiles. Who in turn held love filled eyes. "Thank you." Stiles said back, "I wanna be your mate. But you have to believe me from now on." Derek sighed in relief. "Okay, I'll believe you."
