The days of the five girls on the 22nd floor accompanying each other continued, and more difficulties followed one after another. Fortunately, they already knew each other well enough, and their feelings became increasingly deep, so they could support each other through these difficulties. While Ye Zhenzhen was immersed in scientific research, she was frequently affected by David's family affairs. How to live a simple life became a problem. Fortunately, she was firm in her position and sober enough, and she had a family that loved her enough, and finally solved these difficulties. Fang Zhiheng unexpectedly gained a younger sister, which made her change a lot and gradually return to the right track of life. Zhu Zhe, through years of hard work and accumulation, relied entirely on himself to gain a foothold in Shanghai, and finally broke through the bottleneck of his career. After taking a detour, He Minhong left the 22nd floor and finally returned. He began to learn to think, know how to give, and understand how people should get along with each other. Yu Chuhui relied on external motivation to force himself to work hard, gradually became conscious, steadily rose, and got rid of the shackles of his background. The tests and gifts given by life will continue, but with the support and company of the sisters on the 22nd floor, they can move forward bravely and run towards happiness all the way.
