Fours years flew by, during that time Kai had lived his life in regret. Regretting the time that he had let go of Kyungsoo so easily. He yearned for the touch of his mate, the warmth and fuzzy feelings he would have when Kyungsoo was close by. But he knew that his mate was far far away, on the dark side of the continent. 

Kai sighed heavily as he sat up from the bolder and headed back to his pack. The house still stood tall and fresh even after four years, no one left and no one came in. Their territory was safe, no trouble had occurred ever since Kyungsoo had left. 

Kai was still waiting, thinking about his mate. 

Four years had passed, since he was separated from Kai- his love. He loved Yunho and Jaejoong for sheltering and feeding him, but he only wanted one thing- to feel Kai's warmth once again. He regretted being weak, a weak wolf that wasn't able to fight for himself. He knew that he relied to much on Kai. 
Kyungsoo's eyes dropped as he stared out of the window, looking at the far away mountains, where Kai was. 

Kyungsoo's tears poured as he bit back his sob, he loves Kai. 

Kai wandered the forest, the night was young and cold. The wolf padded across the bumpy paths he looked at the sky, his eyes glistening under the moonlight. Suddenly he whimpered in pain as he clutched his face, his scar was burning- Jack was close by. Kai growled as he knew exactly where Jack was, Kai's birth place. 
The wolf raced down the hills and across the rivers. He arrived at a small cliff, glancing down at a large cave that was embedded into the other cliff. He could feel a presence there, his scar was burning and he could smell the faint aroma of his other half. Kai jumped down the cliff and stood in front of the cave, he slightly growled as he saw a wolf emerge from the dark, a wolf that was identical to him. 

Kai, I knew that you would come

What do you want Jack, why did you come to our territory

Jack shifted back to his human form and smirked as Kai did the same. The two men stared at each other, none of them moved an inch. 
"It's been four years since I last saw your mate, where is he," Jack snickered as he saw Kai's eyebrows furrow. 
" out Jack, he's none of your concern," Kai hissed as he clenched his fist together. 
"He is Kai, we're one, if he's your mate then he is mine as well," Jack glared back at Kai. 
"He is not!" Kai roared as his eyes glowed red.
