Kim Jaejoong is a realistic man who have a firm grip on reality and can see things for what they are,not what they are told they are.   For Kim Jaejoong there's no such things as unicorn,fairy nor mermaid, they are only bedtime story character that never exist.   Kim Jaejoong only laughed and ignored it when his best buddy warn him about the bad luck he will get after he accidentally broke his mirror, he never know that the thing he always thought that is only myth
