"Kai?"    Chanyeol was walking back to his room until he saw Kai leaning on the wall beside Chanyeol's room door.   "Hey." Kai smiled and gave Chanyeol a small wave. Chanyeol smiled unsurely at him and approached him.   "Its been a long time."   "Yeah." Kai nodded and put his hands on his pockets. Silence feels the air for the both of them and Chanyeol kept on looking at random spots. Things with Kai are different now, unlike before, they were like brothers.   "How's Yoora?" Kai suddenly asked. Chanyeol abruptly looked at him.    "She's fine now. At least she's beginning to smile a lot these days." Chanyeol answered Kai truthfully.   Kai smiled bitterly at Chanyeol's remark. "That's good."   "You know, Yoora won't talk about what happened between you two but you know she was devastated when you broke up with her." Chanyeol faced Kai with a serious expression.    "You've been a jerk because you know. You've been dating different girls every week ever since." Chanyeol added, shaking his head in disappointment. "What happened to you? You're not like this before. You did not only hurt Yoora's heart but her pride as well. It seems that those two years that you and Yoora have shared means nothing to you." Chanyeol said straightly at Kai.    Kai looked at Chanyeol with hopeless eyes. "I know. But that's the only way." I have to do it. For her.    Chanyeol looked at Kai confusedly. "What do you mean?"    Kai just shrugged. Chanyeol grabbed Kai's arm. "Kai."   Kai brushed off Chanyeol's hand on his arm. "Nothing. I'm just happy that Yoora is doing fine now."          Kai secretly went to your room and left another note. Yes, he's the one responsible for the notes you are getting. The lines are all from his favorite song. Wonderwall. For Kai, that particular song reminds him of you and for him, you're his wonderwall. You're the best thing that has ever happened to him but due to some circumstances, he must let you go.    He have no choice.         Flashback   "Jong In." Kai's mother called him to go to his father's office. Kai felt nervous. Its been years since he last went there. His father's office is solely just for his father's usage. Also, if his father wants to inform Kai with something very important or if Kai is to be scolded, the location has always been at his father's. Kai grew accustomed that his father's office is a gate to his nightmare. Kai slowly went inside and saw his father sitting on the big chair, both of his arms are on his lap and Mr. Kim's expression is serious.   Mrs. Kim sat on the sofa while Kai was just standing, looking at his father with uncertainty. Mr. Kim stood up and walked slowly to his son.    "You must focus on your studies Jong In. You will be future CEO of our company and you know how big that responsibility is." Mr. Kim said calmly.   "What do you want? My grades are not that bad. I'm attending school regularly. I have a clean record." Kai retorted.   "You are distracted Jong In." His father replied.    Kai gave his father a confused look. "What? Distracted, how come?"   "Kim Jong In, we know how much you fancy Yoora." Her mother slowly said. Kai's eye twitched. He sense something bad news will come.    "I don't fancy Yoora. I love her." Kai proclaimed, looking at his mother and father.   "Exactly." Kai's mother said. "You are both young."   "You liked her. I even brought her here countless times and you have no objections about our relationship
