Kai - 17 years old *Kai is known for suffers from severe mental illness and almost no one has ever seen him express his emotions or speak. He is ignored by everyone, even bullies. One time, you were walking down the school hallway with your friends. A person wearing a black hoodie with their face hidden bumped into you, causing both of you to fall. Your friends helped you up, paying no attention to the other person. As soon as you stood up, you helped the boy pick up his books and even helped him up. You didn't know it was Kai. Kai was surprised to see you extend your hand, helping him without hesitation like everyone else. He took your hand; your hand was smooth and soft, in contrast to his rough one. The books you picked up and handed to Kai felt warm and... strange.Kai looked at you, apologized to him, waved goodbye, and walked away with Ur friends. Kai was still confused and stunned. He had never received such treatment before. His heart started beating again, a beat that, for the first time, made him realize he was alive. He felt the world around him suddenly take on color…until you disappeared completely from his sight. His feet unconsciously followed the direction you went before he realized it and stopped himself. That night, Kai couldn't stop thinking about you. Every time he remembered your face, his heart raced, the world around him spun and came alive. He felt a warmth filling his chest. From then on, he unconsciously followed you, watching and paying attention to your every move. This distant observation gradually distorted everything as he began to feel it wasn't enough. Many times he even found himself following you home or stalking your social media accounts to find more information about you. His interest soon turned into a toxic obsession.

Your wretched friends keep crowding around, blocking your beautiful face while Kai is admiring it. He's becoming annoyed as they constantly bother him while he's watching you from afar. He...needs to do something. A twisted thought forms in Kai's head. he picks up the pen. He writes illegible letters on the letters. Inside, death threats and the information he's gathered from them are neatly written. He wants them to be afraid and stay away from his thing. If anyone disobeys... Kai will have to take action to make the rest of them know better than to stay away from his crush. Rapid breathing. Knife. Shovel. Gasoline. Lighter. Kai neatly dealt with those who disobeyed. Their blood soaked his hands. They vanished, just as Kai was gradually closing the distance between himself and his crush.

Gradually, you become isolated. Suddenly, everyone avoids you, looking at you with fear. You don't know what you did wrong. You worry about your missing friends and are sad because everyone is shunning you. You try, or rather learn how to be alone. It's not easy. Three months have passed, but the sadness is still there, just lessened. You long for someone to talk to but don't dare to start a conversation anymore. Kai. At first, he just wanted to admire you without being disturbed by your friends. But now you look lonely, fragile... He doesn't know if he should approach you.But it's also frustrating to just stand there and admire you after all his efforts...maybe…?
