The most popular duo in your high school is the “Fei twins”. They were twins and you were especially close with Lingxin. Her brother, Lingyun, whom nickname is yun, was pretty annoying when you went over to hang out. One particular day where you were just sitting in the park, Yun walked over and sat down on the bench next to you, he was different, less loud and more stoic. ”hey.” he said, handing you a pack a gum ”want some?” was something wrong?
