Lin Zhenran is divorced, and with her five-year-old daughter Xiaohe, she guards the old apartment and the convenience store downstairs left by her father. The tenants are weird: the programmer who cries in the middle of the night, the aunt who keeps eighteen cats, and the social horror cartoonist who always borrows soy sauce. The convenience store's business is bleak, and it relies entirely on cute cat rice cakes to attract customers. Until he discovered that his hands could "repair" old things - a pair of rusty scissors became extremely sharp, cutting vegetables as fast as flying; a scrapped radio sounded again, broadcasting the last message of the old man's deceased wife. He repaired his neighbor's heirloom pocket watch in exchange for a box of free-range eggs and free water and electricity repairs; he repaired a little girl's doll with a broken leg and gained the trust of all the tenants in the building. But every time he repairs it, there will be a backlash - he will be overwhelmed by the emotional memories left by the items, suffer from splitting headaches, and even suffer from temporary amnesia. His daughter Xiaohe went from being estranged to secretly helping him organize his things. His ex-wife Su Wanqing came back to fight for custody, only to find Lin Zhenran surrounded by beautiful tenant Jiang Xiaolei and gentle kindergarten teacher Chen Jiamu. Old things can be repaired, but what about people's hearts? Lin Zhenran brewed a pot of Kung Fu tea, petted the cat and said: "Take your time, Guan Gong is patrolling the city, Han Xin is ordering troops, there is no rush."
