Zhang is a janitor in a hotel restaurant. He always goes with the flow and is content with the status quo. His love for flight attendant Zheng Youen at first sight changed his unchanging life. In order to get closer to the "Goddess of Acura" in his mind, he joined the square dance team to which Zheng Youen's mother Liu Meimei belongs, gradually changed his prejudice against the big sisters in the square dance, and was impressed by their beliefs and love for life, and picked up the perfect pursuit of industry and life.
Sun, the director of this seemingly demanding hotel suite, implemented a "flash moment" plan to help employees improve. With the support of all his friends, Zhang studied hard, gained opportunities for further study through training, moved towards a broader new world, and continued to narrow the distance with Zheng Youen.
Zhang's obsession and courage have also changed Zheng Youen, a maverick, Wang Niulang, who dared not respond sincerely, and Chen Classic, who gave up the postgraduate entrance examination for fear of failure. Everyone treats others with sincerity in such a big city, and strives to be a better hero in life and create the best of themselves.
