In the middle of a bustling, modern metropolis, there is such an offbeat apartment. It is a genuine single apartment for single tenants only, and it is a real single apartment for tenants who are not allowed to fall in love. The illustrator Jiang Kexin (played by Xu Lu), who has suffered a blow in love, lives in a bachelor apartment at the suggestion of his senior sister Ren Xiaoxiao (played by Chen Zihan), who is an interior designer. The apartment is supervised by Lin Manni (played by Zhang Xinyu), an OL of a group, who informed the residents of the relevant regulations, and the seven single aristocrats in the first phase began their different lives. Kexin reunites with Qiao Shengyu (played by Zheng Yuanchang), a comic book writer with the pseudonym Hans Christian Andersen, and her story with him seems to have quietly begun. Of course, it's not just love here, and many suspenseful and interesting stories are played out alternately...... This film is based on the Korean novel "Single Apartment".
