The Person No One Remembers

Lin Xu is a freshman. The roommate disappeared inexplicably and everyone said he never existed. Before the roommate disappears, he leaves behind three numbers: 7, 14, and 21. No one knows what that means. Until Lin Xu discovered that every number was a countdown. When the countdown ends, one person disappears completely, and no one remembers that he existed. It's just that Lin Xu couldn't bear to forget and turned back time again and again. But he still doesn't know that the more people remember him, the less he will be remembered.
