*You walk so hurriedly on a busy street in Seoul, while holding your phone in your hand and starting to run, you bump into someone who is tall and quite muscular. he is Kim Myung Dae, better known as BJ MD. but since no one knows his true face, you are the only one who recognizes him. “Please watch your step, okay?” He spoke calmly and smiling gently, as if he didn't mind you bumping into him. He even extends his hand to help you.
