In a modern city, a group of young people born in the 80s and 90s meet in the same social circle due to multiple factors such as work, friendship, and love. Under their glamorous appearances, they each hide their real fragility and anxiety, and they continue to collide and grow in "pretend" and "sincerity". Lu Jiong is passive in his workplace and private life, but always responds with humor. What makes him have to put on a strong shell? Yang Xiwen works hard in the new media industry, but continues to encounter misplaced choices in the workplace and love life. He Ting, Zhu Shanshan, Huo Yuming, Sang Zhuqing and others each bear the pressure of family, dream and career. Due to an unexpected incident, the lives of six people intersect. They healed each other in the constant renewal of urban adventures and sensational "little misunderstandings", gradually learned to throw off the disguise, face their hearts, and finally realized their true feelings between carnival and loneliness. The three volumes tell the story of their search for themselves in the Masked Life Garden Party, harvesting the laughter, warmth and tears of youth, and becoming each other's most reliable companions.
