Hidden in an old community in Futian District, Shenzhen is a small building that was transformed into a "shared apartment" - "Deep Love Apartment". Internet operator Lin Chen, who had just ended a three-year relationship, moved in to escape the shadow of his ex; Xia Wan, a new media writer with an out-of-the-box personality, also became a new tenant of the apartment because she "wanted to be closer to the business district." The two met for the first time because they were "stealing the last stove in the public kitchen", and they often crossed paths because they "accidentally took each other's express delivery": Lin Chen helped Xia Wan, who worked overtime until late at night, leave the door open, and Xia Wan picked the lock for Lin Chen who forgot to bring the key (using a spare key given by the apartment manager).
Also living in the apartment are accountant Su Rui and fitness coach Lu Yang, who are constantly fighting each other, apartment manager A Zhe who silently protects Xia Wan, and Xia Wan's best friend Qiao Xin who just got back together with her ex-boyfriend. In Shenzhen, a city that is "too fast to tolerate slow love", they chatted while drying quilts on the public balcony of the apartment, talked while eating barbecue in the urban village downstairs, and shared a bowl of instant noodles in the living room on an overtime night - there was no earth-shattering career counterattack, only The heartbeat hidden in the firewood, rice, oil and salt: it was Lin Chen who remembered Xia Wan not eating coriander, it was Xia Wan who stood up when Lin Chen was being made things difficult by her ex, it was everyone in the apartment who helped Su Rui and Lu Yang resolve their misunderstanding, and it was Azhe who finally dared to say to Qiao Xin, "I have been waiting for you for a long time." In the end, this small apartment became the "harbour of love" for Shenzhen's wandering young people, where everyone found their own warmth and companionship.
