The test of life continues. The five girls on the 22nd floor of the Ode to Joy community also ushered in new challenges and opportunities in their careers, lives and emotions. Ye Zhenzhen began to fall in love with David. The two were very compatible, but she was still inevitably involved in various work criticisms and the tug-of-war between the two families because she was devoted to scientific research; Fang Zhiheng finally walked out of the shadow of the past, but her personality gradually changed. The lively group on the 22nd floor inspired the soft side of her heart; Zhu Zhe was repeatedly suppressed by her superiors, but she believed that there is always a way out, and there are many areas in this society for ordinary people to shine; He Minhong is still experiencing more setbacks. Under the influence of her boyfriend, she is gradually drifting away from the girls on the 22nd floor; Yu Chuhui puts more energy into work and finally walks out of the confusion since graduation. The 22nd floor is like a safe haven. Although there are disputes and doubts between these five girls, they can understand and care for each other more often, help each other, exchange opinions sincerely, face the difficulties of all sizes in life together, and each gain growth and transformation.
