"Kim Jaejae!!!" you yelled for the thousandth time that day calling for her dog that was suddenly missing when she just came back from school. you loved the dog so much and he named him after her crush when she was a freshman at her high school. Kai, her elder brother just got back from his basketball practice and was shocked to see his beloved sister crying in front of their house. He immediately went to his sister and hugged her. "What's wrong girl?" Kai asked while patting his sister's back. "Jaejae is missing," she replied. Kai felt the hurt in him too because he loved Jaejae as his sister loved the dog too. Kai told you that he would skip his next day lesson and find Jaejae for her. Kai brought you on his back then they went inside. The next day, you yelled in front of the house gate when she saw a guy curled into a ball in front of the gate. "Who are you?" she asked. The guy stirred then he woke up and rubbed his eyes. He growled lightly before he said, "I'm Kim Jaejae."
