Following a friend’s advice, Liang Dai Wen attends a stand-up comedy show. By day, Gu Yi works as an editor at a magazine; by night, she performs stand-up at Ounce. She confidently tells her friend Yu Du Le, who also works part-time at Ounce, that she will get the whole crowd laughing that evening. Unfortunately for her, seated right in the front row is Liang Dai Wen, who is incapable of laughing. No matter how hard Gu Yi tries, he just won't crack a smile.
